On the morning of July 4, 2015, 33-year-old Adam Abaker, an African-American/Black taxi driver for Green Taxi, was found slumped over the wheel of his cab near Southwest 26th Street and Robinson Avenue, close to Capitol Hill Elementary School. A passerby who noticed the idling vehicle around 7:00–7:30 a.m. alerted police. Officers found the passenger door open and Abaker covered in blood with obvious signs of trauma; he was pronounced dead at the scene and investigators treated the death as a homicide.

Detectives canvassed the area but had no known eyewitnesses, no clear motive, and no publicly announced suspect. The open passenger door led police to consider that an attacker may have been seated in the front passenger area, possibly posing as a fare, but the investigation produced no definitive leads. Fellow drivers at the Will Rogers World Airport taxi lot mourned Abaker and expressed fear about working alone and handling cash without being allowed to carry weapons. Police continue to seek tips via the homicide tip line.

If anyone knew Adam, saw his cab that morning, or has information about that stretch of Southwest 26th and Robinson around 7 a.m. on July 4, 2015, please contact investigators.
