Gus Adams, 26, who allegedly joined Andrea Miller, 28, in the burglary of Tom Greer's home was arrested the next day and faces a murder charge. Greer, 80, could be charged with manslaughter.
In an interview with KNBC-TV, Tom Greer, 80, said Miller and Adams had broken into his house before. Police said the couple assaulted him when he returned home Tuesday while they were there and then left him lying on the floor, believing him to be incapacitated.
Greer instead pulled out his handgun. He said Miller told him not to shoot because she was pregnant.
"I shot her anyway," Greer said. "The lady didn't run as fast as the man so I shot her in the back twice --she's dead ... but he got away."
Investigators said they are waiting for test results to determine if Miller was telling the truth.
Adams was being held in lieu of more than $1 million bail. He could be charged with murder as an accomplice in a crime that ended in death.
