A Mays Landing man was convicted on all 7 criminal counts in connection with a 2011 fatal three-car collision that left a 9-year-old Hammonton boy dead, and a father and son seriously injured. An investigation determined that William Liepe, now 62, of the 3000 block of Cologne Avenue in Mays Landing, was operating a motor vehicle south on Cologne Avenue when he rear-ended a vehicle driven by Max Guzman, 35, of Hammonton, while Guzman, with two child passengers in the car, was attempting to make a left-hand turn off Cologne Avenue to the athletic fields located behind the fire department. Guzman’s rear-seat passenger, nine-year-old Ryan Schleyer, of Hammonton, was pronounced dead at the scene. Liepe could face up to 30 years in jail for the conviction of aggravated manslaughter.
