Nathaniel Taquan Mangrum, 31, was killed inside the Shades of Blue Bar and Grill on Governor Printz Boulevard in Wilmington shortly after midnight on April 1, 2016. The shooting was reported about 12:39 a.m.; two patrons were struck inside the crowded bar before the gunman fled. Mangrum was treated at the scene, flown by state police helicopter to Christiana Hospital, and pronounced dead. A second patron survived with injuries that were not considered life-threatening.

Investigators quickly identified Wilmington resident Tyerin A. Griffin as the suspect and obtained warrants charging him with first-degree murder, attempted first-degree murder and firearm offenses. Griffin surrendered on September 4, 2016, and was charged; he went to trial asserting self-defense. A jury convicted him of manslaughter under an extreme-emotional-distress theory, first-degree reckless endangering and two counts of possession of a firearm during the commission of a felony; a judge found him guilty of possessing a firearm while prohibited. He was sentenced as a habitual offender to an aggregate 90 years in prison, a sentence later upheld on appeal.

Does anyone who frequented Shades of Blue in 2016 recall events or witnesses from that night?
