NORRISTOWN, Pa. – She called him “Mr. Cosby” and considered him a trusted friend and mentor.

But 20 minutes after Bill Cosby offered her three blue pills and told her to take them with the wine he had set out, Andrea Constand’s legs began to wobble “like jelly,” her eyes went blurry and her head began to throb.

Cosby helped her to a couch in his living room, where she later realized he violated her as she lay helplessly in a stupor, she told police in 2005.

On Tuesday, a judge ordered the 78-year-old Cosby to stand trial on sexual assault charges on the strength of Constand’s decade-old police statement, sparing the former Temple University employee the need to testify at the preliminary hearing.

Cosby could get 10 years in prison if convicted in the case, the only criminal charges brought against the comedian out of the barrage of allegations that he drugged and molested dozens of women over five decades. He is free on $1 million bail.

A trial date was not immediately set.

Cosby, looking less frail than he did when he was arrested five months ago, seemed unfazed by District Judge Elizabeth McHugh’s decision.

“Mr. Cosby is not guilty of any crime, and not one single fact presented by the commonwealth rebuts this truth,” his lawyers said in a statement afterward.
