Stanley Wilson Jr.'s Family Claims Law Enforcement Beat Ex-NFLer Before Death

Stanley Wilson Jr.'s family claims the ex-NFL player didn't simply collapse and die while in police custody last month ... they believe he was actually beaten by law enforcement officials before he passed away.

The attorney representing Wilson Jr.'s family, John Carpenter, said at a news conference on Tuesday photos of Wilson Jr.'s body show the Detroit Lions cornerback was a victim of excessive force before he died suddenly at a Los Angeles County mental hospital on Feb. 1.

Carpenter said pictures of abrasions on Wilson Jr.'s head appear to show he was kicked or stomped. Images of markings on his wrist, meanwhile, seem to reveal he was cuffed at the time of the attack, Carpenter said.

Wilson Jr.'s mom, Dr. D. Pulane Lucas, said county officials had told her the former football player had collapsed and fallen out of a chair while going through the intake process at Metropolitan State Hospital before he died. But, Carpenter said the photos show a "stark contrast to what we've been hearing."

Carpenter filed three claims against L.A. County on Tuesday morning over it all -- one on behalf of Wilson Jr.'s mother, one on behalf of his father, and one on behalf of his estate -- asking for damages in excess of $45 million.

"The County has grossly misrepresented the cause and circumstances of Stanley Wilson Jr.'s death," the attorney said in the court filings.

Carpenter added during the news conference that he has yet to receive Wilson Jr.'s autopsy results.

As we reported, Wilson Jr. had been in custody following his vandalism arrest back in August ... but after he was declared incompetent to stand trial -- he was transferred from county jail to the Metropolitan State Hospital, where officials say he died.

Law enforcement sources told us at the time foul play was not suspected.
