David Flowers was 23 and known to family and friends as Day-Day. On the night of Wednesday, August 26, 2009, Philadelphia police were called to the 200 block of North Simpson Street shortly before midnight and found David in the first-floor living room area of the home with severe head trauma. Fire Department medics responded but he did not survive; one public list records the assault on August 26 and the date of death as August 27, 2009.

Family reflections published with the unsolved case entry say David was beaten to death while he slept, framing the killing as an attack on a sleeping man rather than a street confrontation. He was listed as residing on Kershaw Street, but the available details do not identify a named suspect, motive, or a clear sequence of events leading up to the assault.

If anyone knew David, his movements that night, or has information that could help the Homicide Unit, please come forward.
