In August 2015, former FBI agent Tom Martens and his daughter Molly Corbett admitted killing her Irish-born husband Jason Corbett, insisting they beat him in self-defense with a brick paver and a baseball bat because Jason was choking Molly and threatening to kill her.
Investigators photographed Molly and Jason Corbett's bedroom after the murder. Blood spatter can be seen on the bed.
An investigator measures the height of the blood spatter on the wall in Molly and Jason Corbett's bedroom. The prosecution says Jason's head was 12-18 inches above the ground when he was struck, meaning he was struck when he was down.
Tom Martens used this baseball bat to hit Jason Corbett when, Martens claims, he saw his son-in-law strangling his daughter Molly.
He told investigators he had been spending the night at his daughter's home. After being awakened by a commotion upstairs, he says he grabbed the aluminum Little League baseball bat he brought as a gift for the kids – and ran to her room.
Molly Corbett used this brick to hit Jason on the head. She claims it was sitting on her nightstand in the bedroom because she and the kids planned to paint it for an art project.
Molly also told police that her husband was "screaming 'I'm going to kill you.'"
