A 16-year-old girl was killed and a teen boy was injured after they slipped through an icy lake in Ohio — and a police officer died during the rescue attempt, officials said.

The drowning was reported just before 6:30 p.m. Tuesday near a private dock on the north side of Rocky Fork Lake, according to news station WCPO.

The boy, who was only identified as a 13-year–old, tried to locate the girl under the ice before he freed himself, authorities said.

Divers ultimately pulled the girl from the lake around 11 p.m. — after four hours of being trapped under the ice — but she succumbed to her injuries later in the hospital, WCPO reported.

An Ohio Natural Resources Department police officer who responded to the call also died after he suffered a medical emergency during the rescue attempt, the outlet reported.

Officer Jason Lagore fell ill shortly after arriving at the scene and was brought to the hospital, but he was unable to be resuscitated, officials said.

No further details were released about the circumstances surrounding his death.

"Our hearts are with the family and loved ones of Officer Jason Lagore, who died in the line of duty last night," Ohio Department of Natural Resources Director Mary Mertz said. "Our law enforcement officers and their families carry a unique and challenging burden of responsibilities, and we are deeply grateful for their service."
