A man who attacked a mannequin, that was staged to look like a homeless person under a blanket, has pleaded guilty to attempted murder. 20 year old Shane Schindler faces 8 to 20 years in prison. He attacked the decoy, set up by Las Vegas police with a four pound engineers hammer, after pacing around for 14 minutes on a street corner. The attack was all caught on video. The sting followed a handful of brutal attacks on the homeless, several of them fatal. Police believe Shindler may be responsible for those attacks.
