CHESAPEAKE BEACH, Md. (AP) — Authorities say a 37-year-man has died in a boating accident on the Chesapeake Bay off Calvert County.

Maryland Natural Resources Police spokeswoman Candy Thomson says the man — identified as Salvador Amilcay Santos — was one of five people who went into the water around 3 a.m. Sunday. Thomson says the victims were aboard a small boat that started taking on water at the mouth of Fishing Creek in Chesapeake Beach.

A bystander pulled all five people from the water and began performing CPR on Santos. Firefighters also performed CPR and took him to a hospital, where he was pronounced dead. Santos lived in New Carrollton.

Thomson says the other four people refused medical treatment.

Santos was the second person to die this year in a boating accident in Maryland waters.
