Child dies after being pulled from retention pond in unincorporated Northbrook

NORTHBROOK, Ill. (WLS) -- A young boy died after falling into a retention pond near the Mission Hills complex in Northbrook.

Witnesses said they believe the boy is about 4 years old, and somehow wandered into the pond unsupervised.

According to witnesses, a neighbor rushed to the shore of the small pond to try to revive the boy before first responders arrived. They said he did not appear to be breathing as CPR continued before he was rushed to the hospital.

The Mission Hills condo complex is adjacent to the pond, and in a gated community. Investigators believe the boy came from the condos.

The investigation is being led by the Cook County Sheriff's Department. Detectives went door-to-door speaking to witnesses Monday night.

The Cook County Sheriff's Office said a person died. They did not give any details, including age or gender. .
