PORTLAND -- Law enforcement sources told KGW Tuesday that Parrish Bennette's own father alerted police his son may have harmed his 14-year-old girlfriend.

Bennette's father called police after Yashanee Vaughn was reported missing.

Multiple sources also told KGWTuesday that Bennette, 16, left town shortly after police believe he killed Vaughn. That update was first reported by The Oregonian.

Neighbors told KGW Bennette was in California attending an aunt's funeral. When he returned, juvenile authorities took him into custody on an unrelated parole violation. Bennette was arrested last Thursday and initially charged with murder but then the juvenile court judge reduced the charges to manslaughter the next day.

Sources previously told KGW that there is DNAevidence which links Parrish Bennette to the murder of his 14-year-old girlfriend and that he killed her in his bed.

Grand jury proceedings under way

The grand jury continues to listen to testimony as it reconsiders possible murder charges.

Investigators believe Vaughn was killed by Bennette on March 19th in his home. She was reported missing by her family on March 21. Grand jurors heard about evidence seized when police executed search warrants at Bennette's home, where they believe Vaughn was attacked and killed, along with another location.

The grand jury was also expected to hear from forensic experts at the Oregon State Police Crime Lab.

Meanwhile, on Sunday, searchers wrapped up a third day at Rocky Butte State Park where they had hoped to find Vaughn's body. More:Search for teen's body
