Bill Cosby is facing three counts of aggravated indecent assault in Montgomery County. Here's a timeline of the case and the growing allegations of sexual misconduct against the entertainer.
December 2001: Andrea Constand begins work as director of Operations for the Temple University women's basketball team. In that role, she meets renowned alumnus Bill Cosby, who becomes her mentor and friend.
January 2004: Constand visits Cosby's mansion in Cheltenham Township. There, prosecutors say, Cosby drugs Constand and sexually assaults her while she is unconscious.
January 2005: Constand reports the incident to Cheltenham Township police. Detectives interview Constand and Cosby.
February 2005: Bruce L. Castor Jr., then the Montgomery County District Attorney, says there is insufficient evidence to file criminal charges against Cosby. For a decade, Castor stands by his decision.
March 2005: Constand sues Cosby in federal court in Philadelphia. Though they are not named publicly, as many as 13 other women are prepared to testify against the television star, according to Constand's lawyers.
November 2006: Cosby and Constand settle out of court.
October 2014: During a performance in Philadelphia, comedian Hannibal Buress assails Cosby as a rapist. Video of his remarks, delivered during a standup routine, go viral and suddenly bring a new spotlight to the decade-old sex assault allegations.
November 2014: Cosby cancels public appearances. NBC scraps a Cosby show that was under development.
December 2014: Cosby steps down from Temple's board of trustees.
Spring 2015: Dozens of women come out publicly with allegations of unwanted sexual contact by Cosby. Nearly all their claims are beyond the statute of limitations, some even decades old. Cosby's lawyers say he has never assaulted anyone.
July 6, 2015: A federal judge in Philadelphia unseals portions of Cosby's deposition from the 2005 civil case. In it, Cosby admits to obtaining sedatives to give to women before sex.
July 10, 2015: Montgomery County District Attorney Risa Vetri Ferman reopens the criminal probe into Constand's claim.
August 2015: Investigators travel to Toronto to re-interview Constand about the alleged assault.
October 2015: Cosby becomes a central figure in the race for Montgomery County District Attorney between Kevin R. Steele, Ferman's first assistant, and Castor, who is seeking his old job. Steele runs TV ads claiming Castor failed to prosecute Cosby. Castor counters that Steele could act to arrest Cosby.
Oct. 26, 2015: Constand files a defamation lawsuit against Castor, claiming he undermined her credibility for political gain.
Nov. 4, 2015: Steele wins the election over Castor.
Dec. 30, 2015: Steele announces a charge of felony indecent assault against Cosby, a crime that carries a maximum penalty of up to a decade in prison. Cosby, now 78 and walking with a cane, is released after posting 10 percent of his $1 million bail. His lawyers vow "a vigorous defense against this unjustified charge" and predict he'll be exonerated.
Feb. 3, 2016: A Montgomery County judge rejects Bill Cosby's motion to dismiss his sex assault case, ruling that a promise from the county's former district attorney was not legally binding and didn't bar prosecutors from ever charging the comedian.
May 23, 2016: The Pennsylvania Supreme Court denies Cosby's request to halt proceedings while it reviews the charges against him. Cosby sought to delay his preliminary hearing as he pursued a rare pretrial appeal.
May 24, 2016: Cosby is appears in court in Montgomery County for a preliminary hearing, the first evidentiary hearing in the sexual-assault case. He is ordered to stand trial.
July 7, 2016: A judge rules that the case against Cosby can proceed without pretrial testimony from Constand. The entertainer had tried to have the case dismissed because his accuser was not called to testify at the May preliminary hearing.
July 28, 2016: Cosby withdraws his civil breach-of-contract suit against Constand, dropping his bid to force her to return money paid in a confidential settlement in 2006.
Oct. 12, 2016: The Pennsylvania Superior Court rejects Cosby's attempt to halt proceedings because prosecutors relied on statements Constand gave police instead of calling her testify at the May preliminary hearing. His attorneys wanted the charges dropped or a new hearing ordered at which Constand would be forced to testify.
Dec. 5, 2016: Cosby loses a major legal battle when a judge rules that prosecutors can tell jurors about damaging, decade-old testimony in which Cosby acknowledged offering drugs to women he wanted to seduce. The ruling means the once-sealed deposition can become part of evidence prosecutors use at trial.
Feb. 24, 2017: A judge rules that prosecutors can call only one additional accuser to testify at Cosby's trial, a key legal win for the entertainer.
Feb. 27, 2017: A Montgomery County judge rules that Cosby's trial will be held in Norristown but jurors will be selected from elsewhere.
