SACRAMENTO, Calif. -- A man is accused of killing his 65-year-old mother and 94-year-old grandmother in Sacramento, police said.

Jack Squires, 45, was taken into custody Tuesday night on two counts of homicide, Sgt. Matt Young said.

Police said Squires lived with both of his relatives.

The women were found shortly after 10 a.m. Tuesday on the 600 block of Blackwood Street during a welfare check, Young said.

Neighbor Faye Grundell said Squires was a local handyman and lived in a van parked at his family's house.

"He seemed very immature and just kind of isolated from other adult things," Grundell said.

The identities of the women have not yet been released. Both suffered apparent gunshot wounds, Young said.

The investigation is continuing.
