A 21-year-old Guilderland man with dreams of running his family’s automotive business died Sunday in a jet-ski accident on the Mohawk River.

Although a paramedic and a few police officers frantically tried to save Jack Falvo III by jumping into the water where his friend kept him afloat, he was later pronounced dead from head injuries.

Falvo, of Vosburgh Road, loved the outdoors and had a passion for jet skiing. (See obituary elsewhere in the newspaper.)

A jet ski is a jet-propelled recreational watercraft, smaller than most speed boats, larger than most surf boards.

Glenville Police say the accident happened around 4:45 p.m., in the area of the Freeman’s Bridge Road boat launch. Falvo was riding a jet ski while two friends fished in a boat nearby, police say.

Falvo hit the wake of another boat, was tossed into the air, and hit his head on the jet ski, police say. His friend jumped in the water to save him while another called 911 on her cellular phone, police say.

Officers came to the area and flagged down a passing boater, who assisted them in finding the scene of the accident. Police officers and a paramedic from Mohawk Ambulance all jumped into the water to help Falvo, who was unconscious. His friend was in the water, keeping Falvo afloat, police say.

Falvo was taken to the Alplaus Marina by the Alplaus Fire Department’s airboat. He was then taken to Ellis Hospital where he was pronounced dead, police say.
