Los Angeles police said Tuesday that they believe Christopher Spotz, a 33-year-old man who police say had an "intimate relationship" with Shabani, was involved in her disappearance.
Shabani was reported missing February 23 and was last spotted on a security camera at around 1.15 pm as she left her Hollywood residence with her alleged boyfriend Chris Spotz.
Shabani, 25, was reported missing by her family on February 25 after they were unable to contact her for several days.
Shabani is described as a white female with blonde hair, blue eyes, 5 feet 5 inches tall and weighing approximately 130 lbs., according to police.
The Los Angeles Police Department contacted the office Monday to notify sheriff's officials that they were working an active missing persons case in the area.
"We can not say that conclusively at this point in time because the condition of the remains prohibited positive identification", he continued, adding that they believed Shabani's boyfriend, Christopher Spotz, was "somehow involved in her death".
Spotz took off, and officers with the California Highway Patrol gave chase until the pursued truck exited at Green River Road in Riverside County.
What looked to be a shallow grave was soon found in the area, detectives say. Her mother flew out from Macedonia as friends canvassed the area in a frantic and desperate search.
Shabani came from Macedonia and had been in Los Angeles less than two years, according to her friends. Her family also had hired a private investigator and announced a $25,000 reward for any further information leading to her return.
Investigators had previously searched the Lake of the Woods wildlife area in Nicolaus, California to no avail before they found the remains in Nevada County, Hayes explained.
Spotz initially told authorities that he and Shabani had traveled to Northern California but they had gotten into an argument and he had dropped the 25-year-old off on the side of the freeway.
Spotz had just returned from Colorado where he was spending time with his unidentified fiancée before he shot himself.
"Christopher Spotz was somehow involved in her death and we believe this to be a homicide, however, until the conclusion of the autopsy and our ability to examine the evidence related to the recovery of that evidence we won't be able to determine that definitively", he added.
