The body was discovered off Spenceville Road near Beale Falls, northeast of Beale Air Force Base, according to KTXL.
Authorities say Shabani's death has been determined to be homicide but the cause of death has not been determined, despite visible blunt force trauma to the head.
She was last seen leaving her apartment in Hollywood with her boyfriend, 33-year-old Chris Spotz, on Feb. 23.
The model's boyfriend, who was engaged to another woman and killed himself after a police chase last week, is suspected in her death, Los Angeles Police Capt. Billy Hayes said at a news conference.
A man connected to the missing aspiring actress was found dead after he led police on a chase.
Shabani had been living in Los Angeles for two years when she went missing. The striking blue-eyed blonde's Facebook profile says she studied business administration at American University of Paris after leaving her home country.
Shabani was a student at Stella Adler Academy of Acting, located in the heart of Hollywood, across the street from where the Oscars are held. She was philosophical in many of her social media posts, quoting actor Michael Gambon recently:
"Like a heartbeat. Something inside me. Some dream. I think it's being a dreamer as a child. Dreamy kids become actors, don't they?"
