On the evening of February 13, 2001, Centreville Police Officer Michael Scott Nickerson, 24, and Queen Anne’s County Deputy Jason Schwenz responded to a noise complaint at a mobile home on Hammond Street in Centreville, Maryland. A state trooper accompanied them. A male occupant warned the officers not to enter, then fired a shotgun as they opened the screened-in porch door, striking both Nickerson and Schwenz.

The trooper pulled Officer Nickerson from the porch and attempted to render aid before being attacked by the shooter; the trooper ultimately overpowered and arrested him at the scene. Officer Nickerson was taken to a trauma center and died about an hour later; Deputy Schwenz also died from his wounds. Officer Nickerson was the first Centreville Police Department officer killed in the line of duty.

The shooter was tried and, on May 24, 2002, convicted of two counts of first-degree murder and one count of attempted murder and sentenced to death and life without parole; he later died in custody. Does anyone have memories of the neighborhood or that night that could add detail to the timeline?
