The prosecutor in the  Bill Cosby  case asked a Pennsylvania judge to allow testimony from 19 alleged prior victims of the entertainer  whose retrial on sex assault charges is set to begin April 2.
The request is the first public indication of the shape and parameters of the prosecution case  and it represents a significant expansion of the government’s effort to portray  Cosby  as a serial predator. When  Cosby  was tried in June  prosecutors sought to include testimony from just 13 women who said they had been assaulted by the comic legend.
But it remains to be seen how this latest move by prosecutors will play out: Last year’s effort by prosecutors to introduce so-called “prior bad acts” testimony was largely unsuccessful  as the judge allowed only one of the 13 to appear at  Cosby ’s trial  which ended with a hung jury.

In their request Thursday  prosecutors said that  Cosby  “has spent a lifetime entertaining audiences in front of the camera. Off camera  he has followed and  indeed mastered  a more nefarious script — a victimizing sexual script. . . . To satiate his desire  he has engaged  over the course of a lifetime  in a pattern of serial sexual abuse.”

 Cosby  faces felony charges for allegedly drugging and sexually assaulting Andrea Constand  a former Temple University employee  at  his  suburban Philadelphia estate in 2004.  Cosby   now 80  has denied sexually assaulting women.
