Sheriff's officials said Wednesday an autopsy positively identified the remains were Shabani. She suffered "blunt force trauma to her head," the sheriff's office wrote on Facebook.

The Los Angeles Police Department said Tuesday that Christopher Spotz, a 33-year-old man believed to be Shabani's boyfriend, was involved in her death, but could not elaborate.

Considered a person of interest in Shabani's disappearance, Spotz fatally shot himself after leading officers on a police chase in a stolen truck Thursday. The two reportedly met in acting school.

A native of Macedonia, Shabani moved to the U.S. less than two years ago to pursue an acting career. She had been living in Los Angeles when she was last seen.
