ST. LOUIS:  St. Louis County police say an 11-year-old boy fatally shot a 16-year-old intruder during a home invasion, but some neighbors say they don't believe that account. Officers responded Thursday afternoon to a report of a shooting at a north St. Louis County home. Police Sgt. Brian Schellman says a 16-year-old boy was found dead inside the home and that police believe he was shot after a break-in. But some neighbors told the St. Louis Post-Dispatch that they witnessed the shooting and there was no break-in. Schellman encouraged anyone with information to contact police. Schellman says a second suspect fled but was found a short time later. The 11-year-old and his 4-year-old sister were not hurt. The children's mother wasn't home during the incident but is cooperating with an investigation.
