TWIN FALLS, Idaho (AP) -- Authorities in south-central Idaho have concluded a seven-month investigation and determined a murder-suicide to be the reason two people died in a Twin Falls home.
The Twin Falls County Prosecutor's Office announced Tuesday that 57-year-old Dwight Mein and 48-year-old Ronda Lee Morgan each died of stab wounds.
Authorities tell The Times-News that Mein appears to have hit Morgan in the head and knocked her out before stabbing her to death and then stabbing himself.
Twin Falls County Prosecutor Grant Loebs says the investigation took so long because authorities conducted numerous tests that required lab work to make sure a third person wasn't involved.
A mail carrier on July 29 called police after spotting feet through the screen door of the home and smelling a strong odor.
