A 72-year-old man was arrested on suspicion of attempted murder in connection with the shootings of his two step-grandchildren, authorities said Friday.
Michael Molle, 72, was jailed in connection with the shooting that happened at 8:30 p.m. Thursday at the home he shared with his step-grandchildren in the 2800 block of Tucker Lane in Rossmoor, said Lt. Jeff Hallock, a spokesman for the Orange County Sheriff's Department.
Authorities found the victims with gunshot wounds, recovered a gun they believe was used in the crime and arrested Molle at the home, Hallock said.
A 22-year-old woman was in a hospital with life-threatening wounds, Hallock said. Her 23-year-old brother was recovering after being shot in the wrist, he said.
Their identities were not released.
The shootings possibly stemmed from a domestic dispute, Hallock said, without elaborating.
Neighbors speculated Molle may have been angry with them for hosting a party at the home.
He raised them since they were toddlers, but he had recently asked them to move out of the house, neighbors said. A moving van was seen in front of the home as recently as last week.
Neighbors said Molle, highly intelligent, was recently caring for his wife, who uses a wheelchair.
Rossmoor is an affluent planned community in Orange County.
