Hampton was sentenced under a plea agreement approved by state District Judge Tammy Kemp. She received credit for 303 days already spent in jail, court records show.
The confrontation began Oct. 7, 2025, outside a Five Below store in a shopping center on West Wheatland Road near Interstate 20 in Dallas’ Red Bird area.
According to an arrest warrant affidavit, Simpson was leaving the store with another woman when she held the door open for Hampton. Simpson became upset because Hampton didn’t thank her and the two began arguing, a witness told police.
Simpson and the witness then drove to a PetSmart in the same shopping center. Hampton followed them, according to the affidavit.
Inside the PetSmart, Simpson and the witness told employees they were being followed. Hampton entered the store and began arguing with the witness before leaving and returning. Employees eventually asked the women to leave, according to the affidavit.
As Simpson and the witness were leaving in their car, Hampton threw a bottle at the vehicle, according to the affidavit. Simpson got out and confronted Hampton and the two began fighting.
As the witness tried to break up the fight, Hampton pulled out a handgun and fired three shots at Simpson before running away, according to the affidavit. Simpson was taken to a hospital, where she died.
Investigators identified Hampton after reviewing surveillance footage showing her vehicle leaving the shopping center. She was arrested later that day.
A Dallas County grand jury indicted Hampton on a murder charge in November 2025.
Hampton remained in the Dallas County jail Monday, according to online records, which listed a hold from the Texas Department of Criminal Justice.
