The victims were swimming in Mine Hill Beach at Sunset Lake in Morris County and did not come out of the water, NBC New York reports. Their bodies were later recovered by first responders.

Officials told the New York Post that the search was complicated by underwater vegetation. 

"You don't see it, but there's stuff coming up from the bottom," one person told Eyewitness News. "You can get entangled in it — stuck in it, like seaweed."
