Officer Todd Besser, 49, was killed at his home in St. Michael, Minnesota, on May 9, 2015. The attack also killed his 27-year-old son, Blake Besser. Christopher reportedly left the house, was later arrested at a Monticello convenience store and called 911 to confess.

Christopher was charged with two counts of intentional second-degree murder, and the county attorney announced plans to seek first-degree murder charges from a grand jury; court testimony described the killings as carried out in an execution-style manner. The community of Elk River, where Todd served as a police officer, was reported to be deeply affected.

If anyone knew the Besser family or has information about the events of May 9, 2015, please come forward.
