The area of the cemetery was recently sold to a mosque so the place of worship would have a place for burials, according to Scott Schutzman, the attorney representing families in the suit, KABC reported.
He said the mosque is also a victim.
"I believe fraud was committed and negligence was committed to the mosque who bought the graves. I can't believe that they knew or they would buy occupied graves for their loved ones," Schutzman told KABC.
Detectives were seen digging up a grave. They found a casket that contained human remains 12 feet underground.
"Under the health and safety code, if you recycle graves that have human remains, that's a felony," Schutzman told KABC.
An attorney who represents the property’s owner said he has a report dated two years ago from the Department of Consumer Affairs that calls the allegations unfounded.
The Riverside County district attorney’s office is investigating.
