Novato police tell ABC7 they still can't rule out homicide in the death of a man found buried in his backyard.

Crews dug up Dale Smith's body in February after a neighbor reported him missing. Police say the autopsy didn't detect any obvious signs of trauma on the 74-year-old's body and a cause of death wasn't determined.

A toxicology report completed this week shows no signs of poisoning.

A lawyer representing Smith's wife says he died of natural causes.
