Lekeisha White, 11, was riding her bike around 9 p.m. on a residential street southeast of Middle Tennessee State University when she was hit by Detective Sgt. Ron Killings of the Rutherford County Sheriff's Department, according to investigators.

The girl was taken to Middle Tennessee Medical Center in Murfreesboro before being transferred to Vanderbilt Medical Center in Nashville.

Channel 4 News reported that the child died around 4 a.m. Friday.

The Murfreesboro Police Department is investigating the incident and said Killings has given a blood sample. However, there are no indications that alcohol played a factor in the crash.

Killings, a 12-year veteran of the Rutherford County Sheriff's Department, is on administrative leave.

Officials at the Rutherford County Sheriff's Department said the crash is just a sad, unavoidable accident, but witnesses had a different account.

Witnesses said the deputy was speeding and didn't have his lights on. The witnesses also said that before Killings came to check on the girl, he ran to a nearby yard and tossed out a bottle.

Martina McGill said she picked up the bottle that Killings tossed away.

"It was like, a half-gallon alcohol bottle. I don’t know what kind of alcohol it was," she said.

Rutherford County Detective Dan Goodwin said officers at the scene found no indication that alcohol was involved or that Killings was driving with his lights off.

"Sgt. Killings' record is exemplary and we stand by him. Killings has two young daughters and is understandably devastated by this accident. Murfreesboro police department’s fatal accident crash team (FACT) is investigating this accident. As is standard procedure, Sgt. Killings gave a blood sample as part of the investigation," Goodwin said.

The results of the blood test were sent to the state's lab and could take a few days.

Authorities said they were not ignoring the claims that Killings may have been drinking or threw something out a window, but that if a driver drives on Bradyville Pike, which is a very busy road, lots of beer bottles can be found.

Officials said there are no links to Killings throwing away the bottle.

Goodwin said Killings is one of the department's best deputies and has a spotless personnel file.

Brenda Carneal, White's grandmother, said it's not the first time one of her grandchildren has been hit by a car.

"Just her laughing, the way she kind of does things. She kind of gets to you and makes you laugh. You can't get mad at her," said Carneal.

White, who's from Hopkinsville, was visiting Carneal. White was hit while crossing the street near Gradyville Pike.

"They were putting patches on her chest and everything and trying to hit on her chest so her heart wouldn't stop. The cop car, the front headlight was all busted," said Luis Tronco.
