St. Louis police say they are frustrated and angry that they are getting so little help in solving the murders of children.

Xavier Usanga, 7, became the city’s seventh homicide victim under the age of 17 this year when he was shot and killed Monday while playing outside in the Hyde Park neighborhood. Two other children have been shot and killed in cases that police are investigating as “suspicious sudden deaths.”
