Lieutenant Albert Musterman was shot and killed while making a traffic stop.

Lieutenant Musterman was shot and killed while making a traffic stop on Highway 61, the Daniel Boone Expressway. During the stop the driver of the vehicle approached his patrol car and shot him once in the head as he sat in the driver's seat.

Lieutenant Musterman's killer, William L. Herron Jr, was charged with 1st Degree Murder for the death of Lieutenant Musterman as well as for the murder of the federal witness. Herron plead guilty and was sentenced to life in prison for both murders in 1971.

Lieutenant Musterman served with the St. Charles County Sheriff's Department for 9 years, joining in 1964 after serving with the Webster Groves Police Department from 1960 to 1964 . He was survived by his wife and five sons.
