A man involved in a three car crash in Patterson ran from the scene, but was later caught by Putnam County Sheriff's Deputies on Thursday.   Sheriff Kevin McConville says the 29-year old Nassau County man told Deputies that his actions were intentional efforts to kill himself.  Deputies responded to Route 22 and determined that a southbound vehicle was travelling at a high rate of speed when the driver rear ended another vehicle, with a force enough to send it into a car that was temporarily stopped along the southbound shoulder.  The drivers of the two cars that were hit were transported to Danbury Hospital for medical attention.  Drugs and alcohol were determined not to be factors.  He was charged with felony and misdemeanor reckless endangerment, leaving the scene of an accident, and traffic law violations. He was held at Putnam Hospital Center for mental health evaluation and is required to appear in Patterson Town Court for arraignment on these charges at a future date.
