A woman's remains were found in a trash can partially filled with cement in Victorville and four people were arrested in connection with the homicide on Friday, authorities said.
The remains were found Sunday night after authorities went to a home in the 15000 block of Sitting Bull Street to investigate a possible dead body inside a trash can, according to a Victorville Police Department news release.
Upon arrival, K-9 and the human remains detection dog inspected the trash container and deputies found the skeletal remains inside, according to the release.
Homicide detectives determined the woman had been deceased at the Victorville location for more than a year and that the suspects were friends of hers at the time she died.
The San Bernardino County coroner's office is trying to identify the woman and determine how she died, authorities said.
Detectives found and arrested four Victorville residents on Friday, authorities said.
Lori Rector, 57, was arrested on suspicion of murder and Louis Chacon, 43, and Alphonso Lozano, 36, were arrested on suspicion of being an accessory to murder, authorities said.
The fourth suspect, 31-year-old Jayson Weiss, was already in custody at the West Valley Detention Center in Rancho Cucamonga on an unrelated charge, and he was also arrested on suspicion of murder, authorities stated.
