Was last seen by his son's girlfriend in woods behind Apts. Weather was extremely hot. She stated he was walking and running thru thick brush, briars and wading swampy areas and acting paranoid like he was trying to elude someone. Not staying on trails. She further advised he'd been taking hydrocodone and xanax and she went with him because she was concerned for his safety. She was unable to keep up with him and his family has not had any contact with him since.
