Chris and his co-worker had parked along the shoulder on the southbound side of the New Jersey turnpike near milepost 47.8 at about 5:45 a.m. on October 28, 2008 because they believed another vehicle may have been involved in an accident. When they returned to their truck, Chris was struck by a passing tractor-trailer. He was pronounced dead at the scene. The tractor-trailer did not stop after striking LaRoche. Investigators are looking for the tractor-trailer and driver.
