U.S. marshal shot while attempting to serve arrest warrant in St. Louis County

A U.S. marshal was shot Monday morning in north St. Louis County while on duty, police say.

The marshal, who was not identified, was shot at about 10 a.m. while attempting to arrest 40-year-old William Watson with warrants for assault and domestic assault in the 10300 block of Durness Drive, according to a press release from St. Louis County police.

As officers approached the residence, they saw Watson outside the house, wearing body armor, according to a press release. He began to shoot at members of the Fugitive Task Force, striking one of them. The officers returned fire and retreated. Once Watson moved out of view, the officers formed a perimeter and called for backup from the St. Louis County Police Department's Tactical Operations Unit.

The marshal, a 32-year-old man with 10 years of law enforcement experience with the St. Charles County Police Department and one year with the U.S. Marshals, was taken to a local hospital and was later released.

As officers cleared the scene, Watson was pronounced dead, according to a news release. Two officers, the marshal who was shot and a 23-year veteran with the St. Louis County Police Department, fired at Watson. Police recovered a firearm from the scene.

The St. Louis County Police Department's Bureau of Tactical Operations was on scene assisting and the St. Louis County Police Department's Bureau of Crimes Against Persons will be leading the investigation.
