A 2-year-old boy drowned Sunday in a backyard pool in Linden, according to Mayor Derek Armstead.

Officials say it happened after 6 p.m. at a house on Mckinley Street

Armstead said paramedics worked to resuscitate the toddler, but their efforts were unsuccessful.

The boy was brought to Trinitas Regional Medical Center in Elizabeth, where he was pronounced dead.

As of Sunday night, it was unclear if the boy lived at the home or if he was a guest. News 12 New Jersey was told that the house is his grandmother’s.

It was also unclear as to the sequence of events that led up to the toddler drowning in the pool.

"The City of Linden will do everything humanly possible to try to find out what happened and if there was anything that could have been done to prevent it," Armstead said.
