‘I hit him until I felt he could not kill me’

“I hit him until he goes down and then I step away,” “Thomas Martens, 67, testified. I don’t know how many times I hit him. I hit him until I thought he could not kill me ... I felt both of our lives were in danger. I did the best I could.”
Prosecutors allege Molly Martens and her father brutally beat Jason Corbett to death with a 71cm Louisville Slugger baseball bat and a concrete paving brick. A medical examiner said Mr Corbett was hit in the head at least 12 times. Molly and Thomas Martens are claiming self-defence and the defence of others.
