Arizona Cardinals cornerback Jeff Gladney was killed in an accident in Dallas early Monday morning, according to authorities.
The crash took place around 2:28 a.m. Monday, according to the Dallas County Sheriff's Department. A white vehicle was overturned when officers arrived. Dallas Fire-Rescue confirmed two people -- a male and a female -- were dead. On Tuesday, the medical examiner's office confirmed that the 25-year-old Gladney and 26-year-old Andrea Mercedes Palacios were killed in the crash.
According to the Dallas County Sheriff's Department, the crash involved two vehicles. According to preliminary information, the white vehicle was speeding and clipped the vehicle in front of it, losing control before hitting a beam on Woodall Rodgers Freeway in Dallas. The two people in the other vehicle were not injured.
"We are asking prayers for the family and privacy at this most difficult time," agent Brian Overstreet said in a statement to the Fort Worth Star-Telegram.
Gladney signed with the Cardinals in March after a jury found him not guilty on a felony assault charge.
