Derek Medina's statement to investigators was released Friday. He contends that he only shot 27-year-old Jennifer Alonso because he feared for his own life. Medina claims Alonso first started throwing boxes, shoes and mascara at him, began punching and hitting him and then pulled a knife.
Medina says he disarmed his wife but that she began hitting him again. That's when he says he started shooting.
Medina has pleaded not guilty to second-degree murder with a firearm in the Aug. 8 shooting.
An autopsy report indicates that Alonso was on her knees when she was shot and suffered defensive wounds to her arm.
