BOYNTON BEACH, Fla. (AP) _ A scuba diver drowned while helping his brother retrieve wayward balls from a golf course lake.

Police said Mark Feher, 21, was dragged Monday from the lake at The Links of Boynton Beach by his brother Akos but was pronounced dead at JFK Medical Center in Atlantis.

Authorities say Mark Feher worked for a company that recovers golf balls from lakes.

Both men had full tanks of air when they began diving, but when Akos Feher surfaced at around noon, he could not find his brother.
