Guilford (AP) - Police say the 4-year-old son of a Connecticut police captain has drowned in a neighbor's pool.

Guilford police Sgt. Robert Norman says Tristan Peterson was found at the bottom of a neighbor's swimming pool late Saturday morning. Police say he was taken to the hospital in full cardiac arrest and later pronounced dead.

Tristan was the son of New Haven police Capt. Joann Peterson.

Family friend Joseph Avery tells the New Haven Register that Tristan suffered from Dravet syndrome, a rare and severe form of epilepsy diagnosed in 600 children worldwide.

Avery says police believe the boy wandered into the neighbor's yard and fell into the pool.
