The Rutherford County district attorney has requested another district attorney replace him in the investigation into the death of an 11-year-old Kentucky girl.
Lakeisha White died July 17 after being struck by a car driven by Sgt. Ron Killings of the Rutherford County Sheriff's Office.
In a statement Monday, Bill Whitesell said an attorney for White's family asked him to step down from the investigation.
He said he has requested the Tennessee District Attorney's General Conference appoint a district attorney pro tem.
The family also requested the Tennessee Highway Patrol take over the investigation currently being conducted by Murfreesboro police.
Earlier this month Murfreesboro police suspended the lead investigator in the case after police learned two bottles found at the crash scene weren't initially included in the investigation and there was a two-hour time lapse before Killings had to submit to a blood-alcohol sample.
White's family filed a wrongful death lawsuit for $7.5 million last week.
