Talata Williams was killed last September when a pickup truck crossed the yellow line and slammed into the rideshare car she was taking home from work.
Police said at the time said the pickup was at fault, but no arrests have been made. More than a year later, her family wants answers.
"I leave a message, nobody called back," Deborah Redd, Williams' mother, said. "It's just like she wasn't nothing."
"She was something to me," she said. Williams, who was 43 when she died, also had three children.
Police and the U.S. Attorney's Office for the District of Columbia tell News4 the case is under investigation. They refused to comment.
"One part of me is dead because she's not here anymore," her mother, Deborah Redd, said. "It's just a big empty space."
Redd said her daughter always treated people nicely and always smiled. Williams could make friends with anyone, Redd said.
Williams, of Southeast D.C., called a Lyft rideshare on her way home from work last September.
A Honda Accord picked her up and headed east on Good Hope Road, less than a half-mile northwest of the Skyland Town Center development, when the driver of a Dodge pickup truck headed the opposite direction crossed over the double yellow lines, police said.
The Dodge hit the Honda head-on, pushing it several feet. The force of the crash horrifically mangled the hood of the sedan, video footage from the scene shows.
The Lyft driver and someone driving a pickup truck were seriously injured but survived.
Williams' sister Tiffany Williams spoke to News4 at a vigil days later.
"Why was you on the other side of the street?" she demanded, looking right into the camera. "My sister was on her way home from work. That's all she wanted to do: get home."
