It's always been one of the most enduring mysteries of Bill Cosby's sexual assault case: What drug did he give his chief accuser on the night she says he molested her?
"There was no other goal for that line of questioning except to imply that some sort of nefarious conduct [on the part of the defense] had taken place", Rachel Robinson, defense attorney, said to Judge Steven O'Neill when she requested the mistrial.
Prosecutors wrapped up their sexual assault case against comedian Bill Cosby on Thursday as experts offered conflicting testimony about the drugs he is accused of giving a then-friend before allegedly raping her.
As the legal wrangling continued, Thursday's testimony focused on the unidentified drug that Cosby gave Constand on the night she says he molested her.
Constand said the combination of what Cosby gave her and some wine left her unable to fend off his alleged sexual advances.
Timothy Rohrig, a forensic toxicologist who testified for the prosecution, was the final witness called by prosecutors in their bid to prove that Cosby drugged and sexually assaulted Constand in 2004.
Jackson said the conversation happened February 1, 2004, a few weeks after Constand says Cosby molested her.
She also noted that the prosecution was allowed to present Cosby's civil deposition from 2005 and 2006. All five of the other women who testified said they took pills or drinks given to them by Cosby.
Prosecutor M. Stewart Ryan, during cross-examination, said Montgomery County District Attorney Kevin Steele prosecuted a drug case in 2002 that resulted in the seizure of thousands of illegal Quaaludes. Cosby paid Constand almost $3.4 million in 2006, and his lawyers call her a "con artist" who set him up. That led prosecutors to reopen the criminal case and file charges.
Bill Cosby's defense team attempted again Thursday to declare the case a mistrial over the handling of their star witness Marguerite Jackson, according to Page Six. Constand says she passed out after taking the pills, waking up to find the actor sexually assaulting her.

The judge says there is "simply no grounds for a mistrial" and that Cosby's lawyers are raising the issue too late.
But Judge Steve T O'Neill ruled that Mesereau must limit his questioning to what Constand told Russell about her broadcasting ambitions after he failed to convince him that her earlier alleged drug use was relevant or that she had given inconsistent statements in earlier testimony regarding her views on money.
After jurors heard Cosby's quaaludes testimony, the defense put Jackson on the stand.
Bill Cosby's lawyers have turned to their star witness in the comedian's sexual assault retrial.
But, that same man, who said he was "more than a close friend", also testified he didn't even know Constand had moved to the United States or worked at the college.
Cosby lawyer Kathleen Bliss questioned Constand's mother about Andrea's friendship with Williams and suggested that they were on the outs about a month before Constand went to police.
Outside court, Cosby spokeswoman Ebonee Benson said investigators intentionally ignored Jackson's allegations because they've "always known how damaging this testimony would be".
The judge changed his mind about Jackson for the retrial, giving the defense case a huge boost.
Jackson, who was also a Temple University employee, testified that she had conversations with Constand that included her making a false accusation of sexual assault against a celebrity in order to "get that money" from a lawsuit.
