Norwalk police say a 60-year-old man drowned at Calf Pasture Beach Sunday afternoon.

Authorities say they received multiple 911 calls about an unconscious man in the water at around 4:47 p.m.

Multiple units and first responders were dispatched to the scene.

An officer assigned to the beach arrived later to find people pulling the unconscious man identified as Mauricio Rodas-Garcia, of Norwalk, from the water.

The people at the scene also helped to bring a woman to the shore.

The officer took over from a bystander who had begun CPR on Rodas-Garcia, who was later transported to the hospital where he was pronounced dead.

An investigation determined that Rodas-Garcia and the woman were walking on a partially submerged sandbar before she fell into the water.

She then began having difficulty getting back to the shore due to currents.

Rodas-Garcia went into the water to help but went under water himself and did not surface.

Bystanders that assisted them would locate Rodas-Garcia just under the surface.

The woman was not injured.
