The timeline below was originally created for my own use. When a reference is identified like this: (pdf file #847418, page 42) that means it is one of the files on the FBI/DOJ's web site HERE. There are just too many of them for me to give the actual link for each one. Also, a few links may still only work for me on my own computer. If I'm missing something important, please let me know.2001

1976 - Ivins was a postdoc and Nancy Haigwood was a graduate student in the department of bacteriology and immunology at University of North Carolina (UNC) in Chapel Hill. Haigwood may have gone out for a sandwich with Ivins and his wife together.
1976-1978 (January 1976 to July 1978) Ivins works at the UNC Department of Bacteriology & Immunization at Chapel Hill, NC. He has 2 sessions with a mental health therapist during this time.
1978 - August 27 - Ivins evidently gets a job as a Teaching/Research Associate (Post Doctoral) with the USUHS (Uniformed Services University of the Health Sciences) in Bethesda, MD. He moves to Maryland in the summer of 1978. (FBI Summary, page 47)

1979 - The anthrax outbreak in Sverdlovsk, Russia, reportedly prompts Ivins to become interested in anthrax.
1979 - Haigwood came to believe that Ivins had stolen a lab book from her UNC locker in 1979. Ivins admitted to the FBI that he took the book and later dropped it into a mail box near the UNC campus. He sent Haigwood an anonymous note telling her where it could be found. What now looks significant to some is the use of the mail box. (The FBI summary report says on page 47 that this incident may have been in 1977, before Ivins moved to Maryland, but both Ivins and Haigwood seemed to think it was in 1979.)
Late 1970's - In the late 1970s, Ivins broke into the KKG sorority house at UNC and stole their cipher – a decoding device for their secret sorority rituals – from a locked closet, along with some other ritual documents, though not the ritual book itself. (FBI Summary, page 60) These incidents also seem to have occurred after Ivins moved to Maryland. Ivins was 33 years old at the time.
Dates??? - By his own account, many times over the years, he would drive three hours or more to visit various KKG sorority chapter houses. Once he arrived, he would look at the house for approximately ten minutes and then turn around and drive home for another three hours or more. On two occasions, he actually burglarized the chapter houses and stole secret ritual material, including a cipher used by the KKG sorority to decode the secret rituals. (FBI Summary, page 10)
Ivins, a researcher at the U.S. Army Medical Research Institute of Infectious Diseases at Fort Detrick in Frederick, Maryland, was fascinated with secrets, codes and puzzles, the report said. It said Ivins told investigators that in the late 1970s he burglarized Kappa Kappa Gamma sorority houses at the University of North Carolina in Chapel Hill and West Virginia University in Morgantown to steal ritual books and decoding devices. (Source: Wall Street Journal)
1980 - some say 1983 or 1984 - Ivins entered the KKG sorority building at the University of Tennessee and offered to play the guitar and sing some songs for four members. When they allowed him to do so, he sang KKG ritual songs, which were supposed to be secret. The police were called and he was removed from the premises. (The Expert Behaviour Analysis Panel report says this happened in 1980. FBI pdf file 847444, page 132 says 1983 or 1984)
1980 - December 1 - Ivins resigns from the USUHS to go to work for USAMRIID.

1980 - 29 December - Ivins gets his security clearance to work at Ft. Detrick.
Early 1980's - Bruce Ivins steals a ritual book from a KKG chapter house at the University of Maryland. Copies were made and distributed around campus. FBI pdf file #847444, page 132)
A few years later, Ivins traveled to West Virginia University (“WVU”) in Morgantown, broke into the KKG house there, and stole the actual ritual book from a locked cabinet. He later copied this book, and then mailed it back to the WVU chapter, with a note explaining that his fraternity brother took the book and he wanted to return it. (FBI summary report, page 60)
1982 - During the night of November 28-28, Haigwood's house and her first-husband's car were vandalized, marked with KKG [Ivins had an obsessive hatred of the Kappa Kappa Gamma sorority, of which Haigwood was a member]. Source: Fox News. And page 57 of the Expert Behavioral Analysis Panel report.
1982 - May 9 - Ivins gets a letter published using Haigwood's name in the Frederick News-Post. She knew it had to be Ivins. She confronted him on the telephone. He denied it. Source: Fox News. Ivins later admitted to it (see the EBAP report, page 64).
1984 - May - Ivins puts an ad in the May issue of Mother Jones magazine to contact Carla Sander at a PO box in Gaithersburg, MD, if anyone wants a free copy of the "secrets and initiation ritual of Kappa Kappa Gamma," just send an SASE. (FBI pdf file #847444, page 139)
1985 - January, March, September - Letters are written by attorneys for KKG discussion what action can be taken against Dr. Ivins for trying to sell a KKG ritual code book via an ad in Rolling Stone. (FBI pdf file 847447, pages 9-13)
1988 - Patricia Fellows begins working for Ivins at USAMRIID. (EBAP report)
1993, September 17 - The Frederick News-Post publishes a letter to the editor from Bruce Ivins which seemingly defends pedophilia. After the New-Post publisheds 10 letters attacking Ivins' letter, Ivins backpeddles in another letter in which he claimed his first letter was misunderstood.

2000 - Bruce Ivins contacts his psychiatrist from 1978-79. She has retired, and she refers Ivins to a forensic psychiatrist, Dr. David S. Irwin. (See page 28 of the Expert Behavioral Analysis Report.)
2000 - February - E-mails between Ivins and a friend, also released by the government, show that Ivins sought help in February 2000 from a psychiatrist (Dr. David Irwin) who immediately prescribed antidepressants. Dr. Irwin has five treatments sessions with Ivins and diagnoses him as "homicidal, sociopathic, with clear intentions." Irwin then refers Ivins to Dr. Allen Levy for reasons related to Ivins' health insurance plan and driving distances. (See page 28 of the Expert Behavioral Analysis Report.)
2000 - May - Ivins begins seeing Dr. Levy at Comprehensive Counseling Associates (CCA).
2000 - June - Ivins begins weekly individual sessions with a licensed clinical professional counselor at CCA. The counselor told The Washington Post that she remembers him as precise and unfailingly polite, yet sometimes "very cold, without emotion."
2000 Late June - In his second or third session with the counselor at CCA, and more than a year before the anthrax attacks that killed five people in 2001, Bruce E. Ivins told the counselor that he was interested in a young woman who lived out of town and that he had “mixed poison” that he took with him when he went to watch her play in a soccer match.
“If she lost, he was going to poison her,” said the counselor, who treated Ivins at a Frederick clinic four or five times during the summer of 2000. She said Ivins emphasized that he was a skillful scientist who “knew how to do things without people finding out.”The counselor was so alarmed by her client’s emotionless description of a specific, homicidal plan that she immediately alerted the head of her clinic (Levy) and a psychiatrist who had treated Ivins (Irwin), as well as the Frederick Police Department. She said the police told her that nothing could be done because she did not have the woman’s address or last name. Ivins was 54 years old at this time.
2000 - June - During this same time, Ivins apparently pays Mara Linscott a visit. After returning home, he sends her an email on June 27 discussing his mental problems. Summary report, page 44. In the email, Ivins refers to some incident of paranoia he exhibited "last Tuesday night," so he was at Fellows' home on a weekday. He has also learned that Patricia Fellows is looking for another job. The facts indicate that the "young woman" who Ivins had planned to poison was actually Mara Linscott, who as in her late 20's at the time.

March - Ivins learns that the FBI is again questioning USAMRIID scientists and they're going to interview between 10 and 30 scientists, but not Ivins. ("The Mirage Man," page 218.) This would set off Ivins' paranoia. And, he contacts his lawyer, Richard P. Bricken, to tell him that he might be needed.
Thursday, March 31 - Ivins is interviewed again by the FBI (Richard Lambert and Ann Colbert, according to page 219 of Willman's book) and questioned about the 2 cleanups in December 2001 and April 2002. (pdf file #847444, pages 1 - 23 + 29 - 32) The FBI also asks Ivins why all of his emails from 2001 appear to have been deleted from his computer. The FBI advises Ivins about the mutations found in flask RMR-1029. (FBI summary, page 82) According to page 221 of Willman's book, Lambert concluded after this interview that Ivins was not involved in the anthrax mailings. "Lawrence Alexander and Thomas Dellafera were disgusted by Lambert's conclusions."
A second interview by the FBI with Ivins is conducted at Ivins' home, where the FBI makes a copy of the hard drive of Ivins' home computer. (pdf file #847444, pages 24 - 27)

The Roundtable Discussion of August 18, 2008 contains this statement: "it wasn't until late 2005/2006, that RMR-1029 was the focal point of our investigation as far as from a genetic standpoint." And "So from roughly 2003 to 2006 is when we completed the repository and the screening of the material in that repository."
They say twice in the roundtable discussion that it was in 2006 that the FBI consulted with Dr. Paul Keim at Northern Arizona University and learned that he'd retained his copy of the two slants from flask RMR-1029 that Ivins created in February of 2002.

Tuesday, November 6 - FBI agents review the materials found in Ivins' home. (pdf file #847447, pages 88 - 186)
Thursday, November 8 - Just after 1 a.m., Ivins is observed throwing away his copy of the book "Goedel, Escher, Bach" and a science article about "The Liguistics of DNA." These materials contain the coding and decoding information for the hidden message in the media letters.
Tuesday, January 8 - Someone at Ft. Detrick tells the FBI that Ivins is taking a lot of time off, he's becoming erratic, he's talking about retiring but he's not training a replacement, and he keeps telling people, "I could never intentionally kill or hurt anyone."
Wednesday, January 16 - Ivins is interviewed in the U.S. Attorney's office in the presence of his attorneys. He is questioned about aspects of his personal life - including his fascination with the KKG sorority.

This is mentioned: "The next time IVINS has to testify, he will have to have a proffer." It also appears that a recording of the meeting was made. On this same date, Ivins made his taped "non-denial denial" to a "witness" where he claimed he didn't have any "recollection" of sending out the anthrax letters. (FBI summary, page 70) It seems very possible that there was just one recorded session or meeting on that day and both reports came from that one session or meeting.
Friday & Saturday, June 20 & 21 - Ivins tells someone on-line about his problems, losing friends and being questioned by the FBI. (pdf file #847572, page 51 - 56)

Mrs. Ivins in her note to him the day he died asked why he was paying his attorney so much if he was not going to take his advice. Bruce was leaving Mara anonymous gifts. (After being his lab assistant, she had gone on to receive her M.D.) Source.

(pdf file #847551, page 121) The FBI also executes a search warrant for Ivins' room at Sheppard-Pratt Hospital, looking for the list of people Ivins planned to kill and mentioned in his therapy session. (pdf file #847551, page 136) They also search his home. (pdf file #847551, page 157)

Monday, July 21 - DNA swabs are obtained from Bruce Ivins. (pdf file #847551, page 134)
Thursday, July 24 - Bruce Ivins releases himself from Sheppard-Pratt. (pdf file #847572, page 51) He almost immediately goes to a library and at 7:13 p.m. uses a computer there to access MY web site. It appears he merely looks for the latest news about the anthrax case.
My comment for July 24 is about a CNN interview with FBI Director Mueller where he says "we've made great progress in the investigation" and "there have been breakthroughs."
Saturday & Sunday, July 26 - 27 - Ivins takes an overdose of Tylenol PM. The 911 call is made at 1:06 a.m. (pdf file #847572, page 48) The ambulance arrives around 1:15 a.m. (pdf file #847572, page 43) The 911 call is a call for assistance, not a call about an attempted suicide, so there is minimal documentation. (pdf file #847572, page 125)
Tuesday, July 29 - Ivins dies. (pdf file #847572, pages 46 - 47)
Friday, August 1 - The Los Angeles Times breaks the news that Ivins was a suspect in the Amerithrax investigation, and he has committed suicide.
I decided to put this timeline on this web site because of a conversation I had on Lew Weinstein's forum in April, 2010. In the conversation, I had mentioned that there is a difference between knowing someone is guilty and proving in a court of law that a person is guilty. Someone then asked if knowing someone is guilty is the same as having a theory that someone is guilty. The answer, of course, is absolutely NOT. Theories aren't about facts. Theories are usually based upon past experiences when there aren't any solid facts to work with. Example: The initial theory in the anthrax case was that al Qaeda sent the letters, because the anthrax mailings happened so soon after 9/11. When the facts began to accumulate, however, it became very clear that al Qaeda was NOT behind the anthrax attacks. There was also a theory that the mailer must live in Central New Jersey, since experience says that a culprit doesn't typically drive long distances to a specific area twice to commit crimes. But no facts could be found to prove that theory, either.
This new supplemental page appears to show when the investigators at the FBI knew that they had found the anthrax killer. You can almost pinpoint the exact date: Thursday, July 28, 2005.
There are possible dates before that, too. But, as I've said many times, the FBI is not a Borg Collective. It is not an organization where everyone thinks exactly alike, and when someone learns something, everyone else automatically and immediately learns it, too.
On Monday, May 9, 2005, someone in the FBI submitted a request for all files everyone had on Bruce Ivins. That certainly seems like someone decided that they knew who sent the anthrax letters.
On Thursday, March 31, 2005, Ivins is interviewed and questioned in such a way that Ivins notified the FBI that the next time they wanted to interview him, Ivins wanted his lawyer to be present. That could mean something, too.
But Thursday, July 28, 2005 seems to be a date when virtually everyone at the FBI knew Ivins was the killer. On that date the FBI checked Ivins home to see if anything unusual was going on or if there were any unknown vehicles parked there. There wasn't. That item means nothing by itself. But then, according to the timeline, the FBI seems to go into "stealth mode" for a year and a half, and there is almost nothing related to Bruce Ivins until Thursday, January 30, 2007. It appears the investigators at the FBI knew they had the culprit, but the attorneys at the Department of Justice felt they still didn't have enough evidence to convict Bruce Ivins in a court of law.
What was happening during that year and a half? The scientists assisting the FBI were finalizing the examination of the 1,070 Ames anthrax samples obtained from 15 or so labs around the world, and they were discovering that the scientific evidence from the 1,0707 samples led directly to Dr. Ivins' flask RMR-1029. That flask was the murder weapon. And at some point in time in 2006 they realized/discovered that Paul Keim at Arizona State University (ASU) still had his copy of the slants that Ivins had created in February of 2002. That February, Ivins had prepared two slants from the material in flask RMR-1029. However, even though he had 35 years experience in creating slants, he had improperly prepared those two slants, and, therefore, they were not useable in court. Because the FBI's slant was unuseable in court, the FBI had destroyed it. But Paul Keim still had his copy. And when examined, they found it contained the four key mutations, yet the false replacement slants that Ivins had prepared in April that were also supposed to be from flask RMR-1029 did not have the mutations. Gotcha! Ivins had deliberately tried to mislead the investigation. That's consciousness of guilt.
But, like all prosecutors, the prosecutors in the Department of Justice always want more evidence. The real clincher was the "smoking gun" the FBI investigators found after the thorough search of Ivins' home, Ivins' office, Ivins' vehicles and Ivins' safe deposit box on the evening and night of November 1-2, 2007. Frightened by the searches, a few days later, on November 8, Bruce Ivins threw away the materials which explained the hidden code he'd put in the media letters. When those materials were examined and it was realized what they contained, the prosecutors clearly had a solid case. They knew who sent the anthrax letters and they could prove it in court.
Yes, there is a difference between knowing someone is guilty and proving it in a court of law. And it has nothing to do with any theory.
