Just one day after a man caused a deadly train derailment in Southern California by parking an S-U-V on the tracks -- there's word of a possible copycat incident. Police in Orange County, California, say a suicidal man parked an S-U-V on train tracks this morning.

They say the man was spotted and drove off. And they say that after a chase, a dispatcher talked him out of suicide during a cell-phone call.

Police in Glendale are holding a man on murder charges in connection with yesterday's derailment. They say he was planning to kill himself by driving his S-U-V into the path of a train -- but changed his mind and jumped from the vehicle just before it was hit.
