A longtime Hollywood manager to the stars, Angela "Angie" Kukawski, has died. She was 55.

The Los Angeles Police Department issued a statement on Wednesday indicating that the department’s Valley Bureau Homicide division is investigating Kukawski’s death as murder. She had been reported missing on Dec. 22 in the suburban area of Sherman Oaks, California. She was subsequently discovered deceased inside her vehicle, which was parked on the street in the Simi Valley area.

Prior to Kukawski being identified as the victim, a local Angelino News report said a woman believed to be in her fifties was allegedly found stabbed to death in the trunk of the vehicle.

Police have identified Kukawski’s boyfriend, 49-year-old Jason Barker, as a suspect, and he has been arrested, according to an LAPD press release issued Wednesday.

They believe Barker killed the mother of five inside their Sherman Oaks home, placed her in the trunk of the car and drove to Simi Valley, where he left it parked.

Barker has been booked into the Van Nuys Jail and the Los Angeles County District Attorney’s Office has filed murder charges against him.

The DA's office told Fox News that they have charged Barker with two counts for murder and torture.

They further pressed in their filed complaint obtained by Fox News that Barker murdered Kukawski "unlawfully and with the intent to cause cruel and extreme pain and suffering for the purpose of revenge, extortion, persuasion and for a sadistic purpose, inflict great bodily injury."

Inmate records indicate Barker is being held on a $3 million bond.
