CLEVELAND, BRADLEY COUNTY (WRCB) - According to Bradley County officials, two separate visits were made to Tiffany L. Isaza's residence the weekend she was involved in the head-on collision that claimed the life of 24-year-old Nathaniel Ledford of Cleveland.

At around 11 Saturday night, Cleveland Police responded to a 911 hang-up call on 2360 Blackburn Road at the Springbrook Apartment complex. When police arrived, they were told by Isaza that her boyfriend, Joshua Burgner, had allegedly assaulted her. Police reports say that Isaza had bruising and swelling around her left eye and a bloody lip.

They arrested Burgner on domestic assault charges.

Nearly three hours later, the Bradley County Sheriff's Office visited the same address to notify anyone at the residence of the head-on collision Isaza was involved in.

When they arrived, lights were on and officers claimed to have heard a television. The door was not locked and they entered to find two children asleep in separate rooms. No adults were at the residence and the mother of Isaza, Marsha Neely, arrived and took custody of the children.

Nathaniel Ledford was killed as a result of the head-on collision with Tiffany L. Isaza, 29 of Cleveland.

According to the Bradley County Sheriff's Office, Isaza was traveling north in the southbound lane of APD-40 when her vehicle collided with Ledford's car.

Ledford was taken to SkyRidge Hospital where he died an hour later.

Isaza was taken to Erlanger Medical Center.

BCSO deputies continue to investigate.
