LANSING – Authorities in south suburban Chicago say a 9-year-old boy has drowned in a neighbor's swimming pool.

Lansing Sgt. Detective Scott Bailey says Christian Reese and two young relatives aged 10 and 11 climbed a neighbor's fence Thursday to go swimming. The neighbor didn't know the children were using the pool but heard them screaming that the boy was underwater. The neighbor pulled the boy from the water. The boy's grandmother called emergency responders.

Paramedics found the boy unresponsive and started CPR. They took him to a hospital in nearby Munster, Ind., where the boy was pronounced dead.
