Speaking to DailyMail.com he said: 'We had her in rehab, and two weeks ago he went up there for a family weekend and took her back up to Winder with the kids.
'She wasn't supposed to be there (in Winder). She was in that house with him and Colt, and we went to get her.
'I made a comment that there were holes in the doors and walls, and she said it was Colt.
'As we left Colt came out of the door and started walking down the steps, so I turned to go back to see him, but he said to me: 'I'll *advertiser censored** you up.'
'My daughter and my wife told me to leave it, and again it just shows the environment that he is in. Marcee said he was just showing off.
