Deanthony Clyde Williams was 30 when he was killed outside the Lex on Lowry Apartments in Denver in the early hours of March 15, 2015. What started as a noise complaint—initially mistaken by some for fireworks—turned out to be gunfire. Williams and 28-year-old Tyrael Lamar Adams were both fatally shot; one was pronounced dead at the scene and the other died after being rushed to the hospital.

Authorities said they believed the shooting was gang-related, and the city publicly condemned the violence. A $2,000 reward was offered for information leading to those responsible. Despite the investigation and the reward, the case went cold and no suspects have been publicly identified or arrested.

Does anyone who lived near the Lowry neighborhood in March 2015 remember unusual activity or have information that could help bring answers for the families?
