LOS ANGELES – The Los Angeles County Sheriff's Department refuses to give any specifics about its new investigation into the 30-year-old drowning death of actress Natalie Wood— except to say that her husband, actor Robert Wagner, is not a suspect

The investigation into Natalie Wood's 1981 drowning is being re-opened based on new information, Los Angeles police announced Thursday.

Lt. John Corina, the lead detective on the case, said at a news conference Friday that his office has received "substantial information" prompting the sheriff's department to take another look into one of Hollywood's great mysteries, which was ruled an accidental drowning 30 years ago.

"Recently we received information which we felt was substantial enough to take another look at the case," Corina told more than 100 reporters outside the sheriff's office in Monterey Park. "The case has been assigned to two homicide investigators who will be following up on the information and any other new information."
