A single evening of family dining on Barnegat Bay ended in tragedy when a grandfather’s decision to get behind the wheel of his boat after consuming three beers led to the deaths of his two young grandchildren. Stephen Schneider, 63, of the Bayville section of Berkeley, was charged Friday with two counts of reckless vessel homicide, second-degree offenses, following a crash that killed nine-year-old Mya Bella Golabek and her seven-year-old brother, Sigmund Paul Golabek, both of Lacey.

According to an affidavit filed by State Police Detective I. John Hannan, Schneider told investigators he had consumed two Guinness beers and one Miller Lite in the two hours before the accident. His blood alcohol content on the night of July 19 was redacted from the public copy of the affidavit, but toxicology results from DrugScan Labs, received by state police on August 13, concluded he was “unfit to operate” and that his “alertness, sense of care and caution, perception, judgment, response time and coordination were markedly impaired by alcohol.”

The family had gathered that Sunday evening for dinner at MJ’s Restaurant Bar and Grill on Bay Boulevard in Berkeley. The two children arrived by boat with their parents, while Schneider and his wife, Laurie Schneider, 64, arrived in their own 28-foot Tidewater center-console vessel. After dinner, the children asked to go to their grandparents’ house. Schneider placed them on his boat, seating them at the front in life jackets, he later told investigators from the State Police Criminal Investigation Office and the Ocean County Prosecutor’s Office.

Shortly after 9 p.m., Schneider was operating the vessel through the bay at a speed of about 20 mph. He told detectives he saw the marker “at the last second” before striking it with the boat’s starboard bow. The impact occurred at Intercoastal Waterway day marker No. 39, a single-stanchion, illuminated navigation aid for boaters. The force of the collision ejected both children from the vessel into the bay.

Schneider found his grandson first, then his granddaughter, both face down and unresponsive in the water amid the darkness. He immediately initiated CPR. State troopers from the agency’s Marine Bureau at Point Pleasant Station and Coast Guard members responded after an emergency call made at 9:09 p.m. The children were pronounced dead at Community Medical Center in Toms River.

Laurie Schneider was not seriously injured and refused medical treatment at the scene. Troopers on scene noted that Stephen Schneider displayed visible signs of impairment. He was taken to Community Medical Center, where State Superior Court Judge Dina M. Vicari authorized a search warrant for a blood draw. A registered nurse drew a sample of Schneider’s blood at 12:32 a.m. on July 20.

Schneider told investigators that both the boat’s radar and an infrared/low-light night navigation camera were turned on at the time. He stated that he had spent his entire life on boats, lived close to the restaurant, and had traveled the route numerous times. The charges were approved by Senior Assistant Prosecutor Christopher Heisler following the toxicology results. Schneider remains in the Ocean County jail pending a detention hearing to determine whether he should be allowed to go free until the outcome of the criminal case against him. If convicted, he faces up to 20 years in prison.
