Sgt. Keith Sweeney is charged with second-degree murder in the Nov. 15, 2017, death of 29-year-old Dustin Pigeon. Jury selection began Monday.
The 34-year-old Sweeney was among officers who responded to reports of a suicidal person and found Pigeon doused in lighter fluid and threatening to set himself on fire in a courtyard.
Prosecutors say Sweeney shot Pigeon after another officer fired a bean bag to no effect. An affidavit says Pigeon was unarmed and did not pose a threat when he was shot.
