Officials with the medical examiner’s office say an autopsy was performed Sunday but didn’t reveal the cause of death. They say more tests are needed, including a toxicology screening that can take up to eight weeks to complete.

No arrests have been made. Police say they have been interviewing people who knew Mello.
