DALLAS, Texas — A Dallas woman has been sentenced to 30 years in prison for murdering another woman in a shopping-centre parking lot last year, in a killing that prosecutors and police say began with an argument over a held door and a missing thank-you. Keona Hampton, 23, pleaded guilty to murder on September 23 in the killing of Cecilia Simpson, 41, according to Dallas County court records reported by The Dallas Morning News.

Hampton was sentenced under a plea agreement approved by State District Judge Tammy Kemp, the Morning News reported. She received credit for 303 days already spent in jail, according to the court records.

What happened on October 7, 2025

The confrontation began on October 7, 2025, outside a Five Below store in a shopping centre on West Wheatland Road near Interstate 20 in Dallas's Red Bird area, according to an arrest-warrant affidavit cited by the Morning News. Simpson was leaving the store with another woman when she held the door open for Hampton. Simpson became upset because Hampton did not thank her, and the two began arguing, a witness told police.

Simpson and the witness then drove to a PetSmart store in the same shopping centre — the Wheatland Towne Crossing centre — and told employees they were being followed. Hampton entered the store, argued with the witness, left, and then returned, according to the affidavit. After another argument, employees asked the women to leave.

Outside, in the parking lot, the argument turned physical. According to the affidavit, Hampton threw a bottle at Simpson's vehicle, Simpson got out and confronted her, and the two began fighting. The witness told police Simpson struck Hampton several times before Hampton pulled out a gun and shot her, the Dallas Focal reported from the same records.

Dallas police officers responding to a reported shooting found Simpson with multiple gunshot wounds outside the store. She was taken to a hospital, where she later died, according to the Dallas Focal. Hampton left before officers arrived but was found and arrested later that same day.

A courtesy dispute that ended in a killing

The case has drawn attention across Texas and beyond precisely because of how ordinary its starting point was. Nothing in the affidavit describes a robbery, a traffic crash, or any prior relationship between the two women. They were strangers in the same shopping centre, and within a short span — a door held open, words exchanged at two stores, a bottle thrown in a parking lot — a 41-year-old woman was dead and a woman who was 22 at the time was facing a murder charge.

CBS News Texas, which covered the sentencing, noted the same sequence in its report: the argument over the unacknowledged door, the move from Five Below to PetSmart, the employees asking the women to leave, and then the shooting outside. The guilty plea meant there was no trial, and the facts in the public record rest on the affidavit, the witness account, and Hampton's own admissions to police.

What happens next

With the plea agreement approved by Judge Kemp, the criminal case is concluded: Hampton will serve the 30-year sentence with the 303 days of jail credit the records show. There will be no trial and no further sentencing hearing in the case. For Simpson's family, the sentence closes the court process a little over a year after the shooting.

For readers in the Dallas–Fort Worth area — including the Punjabi and wider South Asian families who live and shop across the Red Bird and I-20 corridor — the case has become a grim local reference point about how fast a public argument can escalate, and why walking away and calling police, rather than continuing a confrontation in a parking lot, is the advice officers repeat after cases like this one.
