Derrick D’Andre Ruff-Shingles, 22, was fatally shot on January 5, 2015, at the Harbor Village Apartments on West 40th Street in Holland, Michigan. An investigation identified 18-year-old Davon Jordan Walker as a person of interest; Walker was taken into custody and charged with manslaughter.

Walker ultimately pleaded guilty to manslaughter after a felony firearms charge was dropped. At his plea hearing he said the shooting was an accident, that he had been playing with a gun, pointed it at Derrick, and it discharged. Derrick’s mother, Lisa Ruff, traveled from Chicago and publicly protested the plea, saying the manslaughter charge was insufficient and that her son and Walker were not friends as Walker had implied; the family also disputed witness accounts.

The plea deal stood despite the family’s objections. Does anyone have information about Derrick’s last known movements or about witnesses at Harbor Village Apartments that night?
