LOS ANGELES (AP) — Detectives have handed the results of their 19-month investigation into sexual assault allegations against Marilyn Manson to prosecutors, who said Tuesday they need more evidence gathered before they can consider criminal charges.

The Los Angeles County Sheriff’s Department said in a statement that on Monday their investigators handed off the case, which involves sex assault and domestic violence allegations dating from 2009 to 2011 against the 53-year-old rocker, to the District Attorney’s Office.

The suit calls her assault allegations fabricated, and said she and another woman used false pretenses including a phony letter from the FBI to convince other women to come forward
