The Maricopa County sheriff's deputies are investigating after a man shot and killed his mother and then turned the gun on himself.
The bodies of Brent McClain, 34, and his mother, Lori Peeples, 62, were found Saturday in a Sun Lakes home after a family member requested a welfare check.
Both had been living together in the home, MCSO Sgt. Calbert Gillett said.
Sheriff's officials say there weren't any signs of forced entry.
Sun Lakes is about 25 miles southeast of Phoenix.
