On November 16, 2009, 15-year-old Jamar Pinkney Jr., a sophomore at Martin Luther King High School in Highland Park, Michigan, was killed in a vacant lot next to his home. His mother alerted his father, 37-year-old Jamar Pinkney Sr., who arrived the next morning and assaulted the teenager in the living room, pistol-whipping and beating him.

Pinkney Sr. reportedly forced Jamar to strip naked at gunpoint, marched him into the adjacent vacant lot, made him kneel, and shot him once in the head as family members tried to intervene. Pinkney Sr. was arrested and charged with first-degree murder, assault, and a firearm offense. At trial the defense argued heat of passion and sought voluntary manslaughter; the jury convicted him on April 1, 2010, of second-degree murder, three counts of felony assault and one count of felony firearm. He was sentenced to 37 to 80 years in prison. An appeal to the Michigan Court of Appeals in 2012 upheld the murder conviction while vacating one assault conviction.

Are there details about Jamar’s life or the neighborhood that could help explain how the case unfolded or provide leads for anyone who knew him?
