Mark Madoff, the oldest son of swindler Bernard Madoff, has reportedly used a dog leash to hang himself in his Manhattan SoHo apartment. His two year old son was in the next room. His wife and daughter were not home at the time. He was discovered by his father-in-law. Mark Madoff wasn't charged in his father's investment swindle, but was the one who turned his father in to authorities.
His wife changed her last name and the last names of their two children due to the stress of the scandal. The death was reportedly due to suicide.
