Preston Allen was an African-American man from Washington, DC, and a father whose life ended in a double homicide on March 24, 2006. Around 2 a.m. police found a parked car on the 400 block of Quackenbos Street NW with Allen and his friend Kristopher Gilmore inside; both men were unresponsive and were pronounced dead at the scene from gunshot wounds. The Metropolitan Police Department’s Violent Crimes Branch took the lead and issued a public reward poster; a reward of up to $50,000 has been offered for information leading to an arrest and conviction.

Online remembrances describe Allen as a warm man who loved storytelling, music, and cars and note the continuing grief of his sons, parents, and siblings. Is there anyone who remembers that night on Quackenbos Street or who has information that could move this case forward?
