He is a 6-1 black man who weighs about 275 pounds. He has black hair and brown eyes. Coleman, who has a "diminished mental capacity," was wearing a long-sleeve black shirt, black shorts and black sandals.

Coleman famously took the field for the Cowboys in the icy Thanksgiving Day game in 1993. He was released from the team in July 1995 and went through a period of drug and alcohol addiction. He returned to Dallas in 2013 after entering a Florida treatment center.

Coleman was reported missing in May but returned safely to his mother's house. His family said he has lingering health issues, including dementia, as a result of his NFL career and splits his time between Dallas and Florida, KDFW-TV (Channel 4) reported.
