BAYONNE — Two brothers drowned at the indoor Lincoln Community School pool Wednesday after lifeguards and first responders could not revive them.

Bayonne police said the brothers, ages 16 and 19, became distressed in the deep end of the pool and could not resurface. Two of the three lifeguards on duty jumped into the water and pulled the brothers out. Along with a third lifeguard, they administered CPR before first responders arrived, according to police.

The brothers later died at Bayonne Medical Center.

Superintendent John J. Niesz said one of the brothers was a recent Bayonne High School graduate and the other a junior.

The indoor pool is open for use by residents in the evening.

An unnamed city official told NBC 4 New York their 11-year-old sister witnessed the drowning.

"The City of Bayonne is in mourning tonight," Mayor Jimmy Davis said on his Facebook page. "I ask that we all respect the privacy of the family, as they deal with this unspeakable tragedy. We all pray for comfort for our neighbors."

The pool will be closed on Thursday. Counselors will present be in schools for students.
