Incident DetailsCause of Death:
Sheriff William Mull and Deputy William Sweem were shot and killed while attempting to arrest a subject who had just killed the family who lived next door to him.
The subject killed a 38-year-old female neighbor with an axe, then shot and killed her 8-year-old son and 9-year-old daughter before walking toward the town square.
Sheriff Mull and Deputy Sweem located the man near the Old National Bank and confronted him. The suspect then shot and killed both officers before fleeing the scene.
The 21-year-old man later died by suicide when he was surrounded by a posse.
Sheriff Mull, from Rockville and a physician, was in the second year of his two-year term in office. He was survived by his son, daughter, four brothers and three sisters.
