WWE legend Jerry Lawler thinks officials in Tennessee and a local sheriff are responsible for his son's 2018 death ... and now he's "seeking justice" in a new lawsuit, TMZ Sports has confirmed.
Brian Christopher Lawler -- aka Grandmaster Sexay -- died by hanging himself in his jail cell in July 29, 2018 following an arrest for DUI and evading police.
But, Jerry claims his death could have easily been prevented -- if officials would have followed proper protocol when dealing with a person they KNEW had a history of suicide attempts in jail.
