Two children aged seven and nine both drown during boating trip with their grandparents

Two young children have died after the boat they were aboard crashed into a channel marker.

The nine-year-old girl and seven-year-old boy were thrown from a 30-foot Tidewater Custom 280 on Saturday night into waters off Berkeley Township, New Jersey. 

State Police said the vessel struck an Intercoastal Waterway channel marker, causing the youngsters to be ejected.

Boat operator Stephen Schneider, 63, and another occupant Laurie Schneider, 64, found the children unresponsive in the water, they said.

The couple are believed to be the children's grandparents, per ABC7.

Sources told Jersey Shore Online that prior to getting on the boat, the group had been inside MJ's Restaurant Bar and Grill. 

The children were raced to the hospital following the crash where Garden State officials said they were pronounced deceased.
