DUNEDIN, FLA. -- It was a low blow, captured on a man's GoPro that has led Pinellas County Deputies to put his estranged wife in jail.

"This is just one of many instances where I've had to use the camera to either prove her guilt or prove my innocence and that's the only reason I am carrying it," said Michael who recorded the attack. 10 News is protecting his identity since he is a victim of domestic violence.

In the middle of a long divorce and custody battle over twin 2-year-olds, Michael has been tying the GoPro to his belt using parachute cord to make sure each exchange with his ex is documented.

"A GoPro has such a wide angle scope on it," Michael said. "It catches everything from five feet away from the feet to the head."

In a custody exchange last Thursday, the camera shows Michael reaching into the back of the car to unbuckle one of his sons. As he is doing that you hear him scream and jerk back. Going frame by frame, in the bottom right hand corner of the video you see what appears to be the hand of 37-year-old Corinne Novak as she forcefully grabs his genitals.
