GAITHERSBURG, Md. (WUSA9) -- One child is in dead after falling through a thin layer of ice in a pond at a Gaithersburg construction site.
Officials say they were dispatched to the intersection of Diamondback Drive and Reprise Drive in Gaithersburg at 4:16 p.m. after a call that three children had fallen into the pond.
Officials said the kids were playing on the ice.
"One had made it off of the ice as our units were arriving, the second was assisted by our units and the third had actually submerged underneath the water," said Scott Graham, Assistant Chief for Montgomery County Fire and Rescue.
A 9 and 11 year old were able to get out of the water but a third child, 10, was submerged for 30-40 minutes before crews were able to find him.
He was transported to a local hospital in critical condition but died a few hours later Monday evening.
"The takeaway from this is that as cold as it was last week in our region there is no ice that is sustainable for human weight. Even pets, keep them all off the ice," advised Graham. "These kids were just out being kids in the neighborhood but tragically it ended tonight for the 10-year-old."
The other two children were also transported to a local hospital. Graham said, as of Monday night, they were in stable condition and being treated for cold weather exposure.
