Deputies say he ran first to the jail’s south tower yelling that his wife was after him and trying to hurt him. Then he went to the main lobby claiming she was trying to kill him.

A spokesperson for the department says the man was behaving erratically and would not calm down before officers had to restrain him. That’s when the man collapsed, and deputies began CPR until paramedics arrived to take him to Parkland Hospital where he was later pronounced dead.

One witness says the man seemed to be having some sort of health problem as soon as he parked his truck in the crosswalk.

“He jumped out of his truck with his chest, holding his chest like this,” said the witness who asked to be identified only as Gregory G. clutching his own chest,  and walked up here, and I walked up behind him, and I said maybe you’ve been shot in the chest or something.”
