Dallas police recovered a black Hyundai that may have been involved in a fatal hit-and-run crash.
Daryl Sirls, 48, has been charged with failure to stop and rend aid. He was earlier taken into custody on an unrelated charge and was questioned about the hit-and-run.
His mother noticed damage to the car Tuesday morning and called police.
Sirls called 911 and told dispatchers he believed he hit someone but was unsure. He told police he didn't wait for officers to arrive because he has health issues and needed to go home and get medication.
"He fulfilled part of it in that he made the call, but he didn't stay around to leave identification," Lt. Scott Bratcher said.
The victim, whose name was not released as of Tuesday evening, was hit and dragged along the street.
A neighbor told NBC 5 she called 911 after hearing a loud bang and saw the victim lying dead in the street.
She also said she saw a vehicle that likely hit the man sitting just down the street. The vehicle later drove off, she said.
