NORRISTOWN, Pa. (AP) — The Latest on Bill Cosby's preliminary hearing in his Pennsylvania sex-assault case (all times local):

9:10 a.m.

Bill Cosby is in a Pennsylvania courthouse for a key hearing in his criminal sex-assault case.

Dressed in a dark suit, Cosby waved toward cameras and walked into the courthouse in Norristown on Tuesday morning.

His preliminary hearing will determine whether prosecutors have enough evidence to send the 78-year-old entertainer to trial.

Cosby is accused of drugging and molesting former Temple University employee Andrea Constand at his suburban Philadelphia mansion in 2004.

Cosby says they engaged in consensual sexual activities.

It's not known if Constand will testify or if police will instead read her statement about the encounter that night.

Cosby faces up to 10 years in prison if convicted of aggravated indecent assault.
