Authorities have charged two men with the murder of retired St. Louis Police Captain David Dorn after a handful of looters broke into a pawn shop in north St. Louis City.

The St. Louis Circuit Attorney’s Office has charged 24-year-old Stephan Cannon with first-degree murder in Dorn’s death on June 2 outside Lee’s Pawn and Jewelry following a night of looting and violent rioting in the city.

Mark Jackson, 22, also has been charged with one count of second-degree murder, one count of robbery, stealing and armed criminal action.

Dorn retired from the St. Louis Police Department in 2007 after 38 years on the job, during which he rose from rookie patrol officer in 1969 to captain. He was the deputy commander of the Bureau of Patrol Support, which oversees traffic and mounted patrols, commercial vehicles and the tactical unit.

After his retirement, he became police chief in Moline Acres in 2008.

“He was the type of brother that would’ve given his life to save them if he had to,” the Ethical Society of Police of St. Louis wrote after the murder. “Violence is not the answer, whether it’s a citizen or officer.”

Dorn’s wife, Ann Marie Dorn, a sergeant with the St. Louis Police Department, told the St. Louis Post-Dispatch her husband was a friend of the pawn shop’s owner and worked for him. He would show up at the shop when burglar alarms sounded to check on the building and make sure it was secure.
