Here is my observations from reading some news reports, the full filing by Egan and the sections that where available in the FBI Criminal complaint pdf as posted by TMZ. Because of all available documentation, there are issues that arise in egan's story that can make my observations rather confusing.
PLEASE NOTE: IN RELATION TO THE FBI CRIMINAL COMPLAINT DOCUMENTS, EGAN IS “MINOR #4”, SCOTT SHACKLEY IS “YOUNGER BROTHER”, CHAD SHACKLEY [SCOTT’S OLDER BROTHER] IS “SHACKLEY” AND MARK COLLINS-RECTOR IS “RECTOR”
TMZ’s posted FBI criminal complaint document now has Mike Egan at age 15 when he graduated 9th grade in 1998. Thus that means that Mike Egan is now 30 years of age. All reputable news outlets are reporting he is 31 which would then make him 16 at the time of the incidents. TMZ reports that Egan says his mother went to the FBI and LAPD back in 2000 while variety is reporting that it was 1999. The truth now is that both the FBI and the LAPD interviewed Egan on July 20th, 2000. The Hollywood reporter states that he was sexually abused by the X-Men director beginning at age 15 through age 17 as per the press conference. Lets do the math. Most news outlets are running that Egan is 31. Egan said the abuse started at the age of 15, According to the court documents filed by Egan was first taken to estate in "early-mid 1998" but according to the FBI documents “Minor #4 graduated from the ninth grade in May, 1998, at the age of 15. After the graduation ceremonies, the younger brother invited Minor #4 to a graduation party at Shackley’s house located at (the “Encino Estate”

. They took a limousine to the party at approximately 9:00 p.m. There were approximately five to six guests at the graduation party including RECTOR and Shackley.” The Abuse started that night. If we go with media reports that he was at the age of 31 would place him at 16 years of age, but the thing is that he claims that he was 15 at the time which would make him 18 in June 2000 to May 2001, when he sued 2 other men including Mark Collins-Rector. The thing is, according to court documents "On more than one occasion, Plaintiff was flown to Hawaii when he was 17 years old. Two of these trips took place on or between August 1, 1999, and October 31, 1999" which means that with his graduation at 15 when the abuse started, its possible for him to be 17 for the two cases of abuse but with no solid birthday this can be assumed and then we could pin point his birthday to August to October. But Egan said the abuse started with Mark Collins-Rector "Approximately 2–3 months" prior to him meeting with Bryan Singer. The Only way for the abuse to have started by Bryan Singer would be when Egan was at the age of 15 would be between August though late September of 1998, even though he first went to estate and met Mark Collins Rector, as the FBI document states May of 1998. That thus means that it is not possible for Egan to be 17 years old on August 1st, 1999. That would place him as being born in 1983 in October and then would he be 17 during on October 31, 1999. Thus it is not mathematically possible for Egan to be 15 years old when the abuse started with Bryan Singer in August though October of 1998 and still be able to be 17 years old for both August 1, 1999, and October 31, 1999 when he was apparently 17. So If he was 15 at the time the abuse started when he met Bryan Singer at the age of 15, I would pin point that to August 1997 though Mid-1998 just to be able to be 17 at the time of August 1, 1999, and October 31, 1999. If we are to use his age as indicated though the FBI document, If he was 15 at the time the abuse started when he met Bryan Singer at the age of 15, he would NOT be 17 for August 1, 1999 as the abuse would of started during the months of August-September when Egan as 15, as a birthday would be in October but then would Egan possibly be 17 for October 31, 1999. I would estimate Mike Egan’s Birthday to be in October of 1983 to be 15 when the abuse started and to still be 17 for the time for October 31st 1999 for an purported incident in Hawaii. It is worth noting that Egan continued working for Shackley until May of 2000 as per the FBI document but in the pages that are available that was about Egan 27,28,30 and 31 (PDF Pages 37-41) there are NO mentions of Singer nor Hawaii. Also in order for him to now be 31 as per the news reports, Egan would have to be born between Late may-mid october of 1983 to be 31 but then not able to be 15 when he was abused by singer, but if he is 31 then his birthday Late may of 1982 to late may of 1983, then he would be 16 when the abuse started. It's also to note that Bryan Singer would be in Canada when X-Men was filming which mind you took place from September 22, 1999 to March 3, 2000 in Toronto and in Hamilton, Ontario, so it would make Singer look bad just from the standpoint of leaving the filming within a month since the start of the filming to go to Hawaii for one week, and leaving the filming for that one week, he would of not directed X2 or Days of Future Past.
