Oof. This is so sad. On Saturday night, Dog the Bounty Hunter's stepson Gregory Zecca accidentally shot and killed his 13-year-old son, Anthony, at their Naples, Florida, apartment. Now, Gregory has been placed on a psychiatric hold because he is in so much grief over the shocking loss. A rep for the family told TMZ on Monday evening that Greg was put on a 5150 psychiatric hold because he's "so devastated" by the death, raising concerns that he might try to take his own life.
