Bill Cosby's first trial in Norristown ended on an inconclusive note – a hung jury and a mistrial. But as his second courtroom showdown against accuser Andrea Constand opens April 9, the retrial is shaping up to be no simple repeat. Click here for the latest developments, and read on for everything you need to know about the case.

What happened last time? After five days and 52 hours of deliberations in June, the first jury to weigh the case against Bill Cosby reported that it was hopelessly deadlocked, prompting Montgomery County Judge Steven T. O'Neill to declare a mistrial and setting up the second trial playing out in Norristown this month. The last batch of jurors described hours of tense deliberations, with some saying they were completely convinced of Cosby's guilt, while others would not be swayed from their position that Constand was unconvincing on the witness stand.

What was Cosby's alleged crime? Constand says that during a visit to Cosby's Cheltenham mansion in 2004, Cosby encouraged her to take three blue pills after she complained of a headache. She told police that the next thing she knew, she was fading in and out of consciousness and woke up the next morning with her sweater bunched up around her and her bra undone. Cosby has admitted they had sexual contact that night, but maintains that it was consensual and that the medication he gave her was just an herbal remedy.

What are the charges? Cosby is charged with three felony counts of aggravated indecent assault around that single encounter with Constand. If convicted, he could face up to a decade in prison.

Who is Andrea Constand? At the time she met Bill Cosby, Constand was working as the operations manager for Temple University's women's basketball team. Cosby, a university trustee, took an interest in her, and they became friends. Constand has described him as a mentor, but insists she had no romantic feelings toward him as she is gay. After her alleged assault, Constand moved back to her hometown of Toronto, Ontario, where she now works as a massage therapist. But Cosby's defense aims to paint the 44-year-old as a gold-digging opportunist who they say once told a confidant of a plan to fabricate her assault claims to extort money from Cosby.

Why is Cosby being tried more than a decade after the alleged assault? Constand first came forward in 2005, a year after her alleged assault, but then-Montgomery County District Attorney Bruce Castor declined to bring charges, saying he didn't believe the case would stand up in court. After that decision, Constand filed a civil suit against Cosby, which they settled out of court in 2006 for an undisclosed sum. But as the Cosby scandal reignited in late 2014, interest in Constand's claims was revived. A federal judge in Philadelphia unsealed excerpts from Cosby's deposition in the civil suit, which led a new Montgomery County District Attorney, Risa Vetri Ferman, to reopen the criminal investigation and to charge Cosby in December 2015.

What does the jury look like this time? The court chose 12 jurors — seven men and five women — and six alternates during a four-day process in Norristown that ended April 5. Only two black jurors were selected, with three alternates, prompting Cosby’s lawyers to lob accusations that prosecutors were intentionally trying to keep African Americans off the jury. (They later withdrew that complaint). All but one juror said they had prior knowledge of Cosby’s legal woes – one even admitted she thought Cosby was guilty. But all vowed to set their opinions aside. Several also said they had friends or close relatives who had been victims of sexual assault. (READ MORE: Bill Cosby jury selected: 7 men, 5 women)

How will the #MeToo movement affect the trial? Although jurors will be instructed to focus only on the allegations and evidence presented in the courtroom, the shadow of the #MeToo movement has loomed large over the run-up to the retrial. Since the last trial, the cultural landscape surrounding public awareness of sexual assault by powerful men has shifted dramatically. Powerful Hollywood icons such as Harvey Weinstein and media figures such as Matt Lauer have been brought down by accusers who say they felt empowered to come forward amid a wider public reckoning with the entertainment industry's casting-couch culture. Cosby's lawyers have expressed concern that it will be impossible to find jurors who can set aside their feelings about other celebrity sex assault allegations.

Bill Cosby plays the drums as he returns to the stage in Philadelphia on Jan. 22, 2018, for the first time since a sexual assault scandal appeared to force him into an early retirement. He also told stories and jokes at LaRose Jazz Club in Germantown.

Will Cosby testify? He did not take the witness stand during his first trial, and Cosby's new legal team has given no indication of a different approach the second time around. Yet in the months leading up to his second trial, Cosby appeared to be making a concerted effort to remind his hometown of Philadelphia why he was once so beloved. He delivered a surprise stand-up performance at a Germantown jazz club in January and invited reporters to tail him to dinner at a Pennsport restaurant.

How many accusers will testify? More than 60 women have come forward since 2014 to accuse Cosby of sexual misconduct dating back decades. But the judge has limited prosecutors to calling only five, aside from Constand, as witnesses. They include supermodel Janice Dickinson, one of Cosby's most vocal critics; Janice Baker Kinney, a former bartender; and three once-aspiring actresses – Heidi Thomas, Chelan Lasha, and Lise-Lotte Lublin. All say Cosby drugged and assaulted them after approaching them as a mentor in the '80s. Missing from that list, however, was Kelly Johnson, a former talent agency assistant who was the only other Cosby accuser allowed to testify at his first trial.

What is the evidence? To bolster Constand's claims, prosecutors are presenting evidence they say shows that Cosby acted in the way she describes.

*Constand’s testimony. The last trial featured the first public testimony from Constand, who had remained silent for 11 years under a nondisclosure agreement she signed as part of a settlement with Cosby in 2006. Her police statements from when she first came forward provided a preview of her testimony, although Cosby’s defense team then used them to suggest that her story had changed over time.

*The deposition. In a 2006 deposition as part of Constand's civil suit against him, Cosby discussed buying the party drug Quaaludes to use in what he described as consensual sexual encounters with women. (READ MORE: Jurors hear Cosby's description of liaison with Constand: 'I am not stopped' | Ending with Cosby's own words, prosecution rests)

*The recording. A year after the alleged assault, Constand’s mother secretly recorded a phone conversation she had with Cosby in which he admitted having sexual contact with her daughter and offered to fly Constand and her mother to meet him. Cosby’s lawyers say the recording was made illegally. (READ MORE: Cosby suspected his call was recorded, prosecutors say)

What does the defense say? Cosby’s new defense team has already proven itself willing to lob attacks at Constand that his previous lawyers deemed too risky or too unseemly. Pretrial arguments suggest the team intends to say she fabricated her claims against Cosby in hopes of extorting money from him. Unlike in the first trial, the defense lawyers intend to make the financial settlement Cosby paid Constand in 2006 a centerpiece of their case. They also intend to call a witness – one of Constand’s former Temple University coworkers – who claims that Constand once told her that she could make up sex assault claims against a celebrity to win a financial payday. (READ MORE: Bill Cosby’s payout to Andrea Constand will be revealed at trial, judge rules

Who are the lawyers? After parting ways with the defense attorneys from his first trial, Cosby now has a legal team led by Tom Mesereau, a go-to Hollywood lawyer whose past clients include Michael Jackson, Mike Tyson, and Baretta star Robert Blake. Joining Mesereau on the defense team are former federal prosecutor Kathleen Bliss, appellate expert Becky S. James, and Montgomery County attorney Lane Vines. On the prosecution side, Montgomery County District Attorney Kevin R. Steele is leading the government's case against Cosby. In his first run for office, Steele was elected in late 2015 with a campaign that ran television ads focused on the Cosby case.
