Staff Sgt. Johnny Clyburn, 41, was shot and killed at his Detroit home on the morning of Tuesday, May 27, 2014. A 21-year veteran assigned to the 127th Security Forces Squadron at Selfridge Air National Guard Base, Clyburn had just returned from an overnight shift when the shooting occurred around 7:30 a.m.

Police identified his 19-year-old stepson, Antonio Hicks, as the alleged shooter. Hicks is also accused of shooting his mother and Clyburn’s fiancée, 40-year-old Nicolina Pace; Pace was shot twice, managed to call 911 and identified her son, and was hospitalized in critical condition. Hicks fled but was found and arrested about an hour later, roughly three miles from the house, and taken to a hospital for a mental evaluation. Authorities said he had a history of mental illness and may have been off prescribed medication.

Clyburn was remembered by friends and colleagues as devoted to God, family and country; his commander, Col. Philip Sheridan, called him a valued member of the team. Does anyone have information about Johnny Clyburn, Nicolina Pace or that morning that could help clarify what happened?
