ALBANY, N.Y. (AP) — An 11-year-old girl who fell through the ice while trying to help a 12-year-old boy who plunged in before her over the weekend has also died, authorities said Tuesday.

The two children were at Washington Park Lake in Albany at about 4:30 p.m. Saturday when the boy tried to walk across the frozen lake and fell through the ice, Albany police said in a news release.

The girl followed to try to help the boy but she fell in also, police said.

Albany police officers and firefighters responded and rescued the girl, who was taken to Albany Medical Center Hospital in critical condition. On Tuesday, police said the girl had died from her injuries.

A New York State Police dive team found the boy’s body at about 7:30 p.m. Saturday, police said.

Albany Mayor Kathy Sheehan said it was surprising that the children made it as far as they did, given how thin the ice was.
