TWIN FALLS, Idaho (AP) -

A southern Idaho prosecutor says he's still waiting for final autopsy results to determine how two Twin Falls residents died three weeks ago.

The Times-News reports Twin Falls County Prosecutor Grant Loebs said Thursday that he doesn't yet know if charges will be filed in connection with the deaths.

Fifty-eight-year-old Ronda Morgan and 57-year-old Dwight Mein were found dead July 29 when a mail carrier became suspicious and looked in the front door, spotting one of the bodies. One of the bodies was more decayed than the other, making it difficult for authorities to immediately determine the cause of death.

Twin Falls city spokesman Joshua Palmer says police are not looking for a suspect and believe this was an isolated incident with no threat to the public.
