Cosby, the famed comedian, declined to testify in his own defense, and his defense rested after calling just one repeat witness for further questioning.
The defense consisted of a single witness: Sergeant Richard Schaffer of the police department in Cheltenham, Pennsylvania, who already testified for the prosecution and who investigated Constand's case in 2005. Lawyer Brian McMonagle said in his closing argument that while Cosby had been unfaithful to his wife, he didn't commit a crime.
Cosby confirmed to the judge that it was also his wish that no other witnesses than Schaffer be called. He has said the encounter was consensual.
It remains to be seen whether any of that-or the sight of his supporters, like The Cosby Show's Keshia Knight Pulliam, or his wife, Camille, who made her first in-court appearance today-will be enough to sway jurors from the prosecution's far lengthier, more compelling case.
A Pennsylvania prosecutor says "fancy lawyering" can't save Bill Cosby from his own admissions about fondling a woman after giving her pills he knew could put her to sleep. Furthermore, McMonagle cited Constand's repeated inconsistencies she presented throughout her two-days of testimony, including the police report.
Cosby isn't expected to take the stand, he has pleaded not guilty to the charges.
Jurors will hear closing arguments and could perhaps start deliberating Monday afternoon.
Cosby is not charged with abusing Johnson, but prosecutors called her to the stand in an effort to persuade the jury that he employed a familiar pattern when he allegedly assaulted Constand.
Constand initially told police she had not been alone with Cosby before the alleged assault and that she had little contact with him afterward. But on Monday morning, Cosby, under oath, told Judge O'Neill emphatically that he has chosen not to testify in this case. Cosby said before the trial that he does not plan to testify, though Wyatt suggested last week that "nothing's ever off the table". Constand said she had to return calls from the Temple University trustee because he was an important booster and she worked for the women's basketball team.
The defense had been building the argument that Constand gave inconsistent statements, and with that, the defense rested.
McMonagle also argued that Constand was romantically involved with Cosby before deciding to manufacture the story of an assault to support a civil lawsuit. The couple have four daughters. Cosby's spokesman said last week that the comic might take the stand, but his lawyers were mum.
McMonagle, a prominent Philadelphia defense attorney, accused Constand of telling "a stone-cold lie".
