Police in St. Louis County are looking for a 15-year-old boy after the shooting death of a 3-year-old boy.

County police spokesman Brian Schellman said the toddler was shot once in the abdomen Monday morning at a home near Florissant and died later at a local hospital. He said investigators don't yet know if the shooting was an accident.

The 15-year-old is described as a family acquaintance, who ran from the home on foot. Several adults were reportedly in the home at the time.

The St. Louis Post-Dispatch (bit.ly/1OhRja5 ) reports that police canine officers are searching wooded areas near the home for the teen suspect.

A neighbor told the newspaper that the home's owner had been transferred out of town and was renting out the property.
