There is new information on the pro football player from Long Island who killed his girlfriend and himself.

Autopsy results show West Babylon's Jovan Belcher suffered from a brain disease found in athletes with a history of repetitive head injuries.

Belcher shot his girlfriend then himself nearly two years ago, but lawyers for his family just released the findings. 

The family is suing the Kansas City Chiefs, accusing the team of failing to provide adequate medical care for Belcher.

The Chiefs haven't commented on the autopsy.
