Police say a 14-year-old boy drowned Thursday evening in a pool in Aquebogue.

Riverhead police say the boy, whose name is not being released, was found unconscious and without a pulse in the pool on Crystal Drive around 5 p.m. He was given CPR, but it was too late. The teen was pronounced dead at the Peconic Bay Medical Center.

The incident marks the sixth drowning on Long Island this summer, five of which took place in pools.

Diana Price, of the Nassau County Red Cross says supervision is mandatory when it comes to children and water. She says drowning can happen anywhere.

If a child or adult goes under the water, Price says, only those who know how to swim should attempt a rescue. Call 911 right away, get the individual out of the water and administer CPR.

Price says nothing beats a watchful eye, but having lot of flotation devices in pools and an alarm is very helpful.
