No motive yet for murder of 80-year-old woman

There's still no clear motive known for the murder of an 80-year-old Dallas woman. Police say her granddaughter was the one who killed her.

A Dallas woman is charged with murder after she told officers she had shot her grandmother, according to an arrest affidavit acquired by FOX 4.

30-year-old Kelsie Miles showed up to the Grand Prairie Police Department Sunday morning around 5 a.m. She told police she had shot her 80-year-old grandmother, Betty Lou Hearn, at a home they shared on Colwick Avenue in East Oak Cliff in Dallas.

Police say Miles confessed to the killing. But in court documents obtained by FOX 4 Monday, police did not specify a motive.

Dallas police were called to do a welfare check at the home. No one answered a knock at the door, so officers forced their way inside and found Hearn dead with a gunshot wound to the head, according to the affidavit.

Miles told police she had the gun she used in the shooting in her car. Officers recovered a Smith and Wesson .380 from the car, according to the affidavit.

FOX 4 crews captured Miles' car being towed from the Grand Prairie police station.

For as long as neighbor Nathan Jackson can remember, Hearn acted as a second mother.

"Me and her kids went to school together and grew up together on this block," he said. "She treated us like her kids. She was a good lady."

Jackson says he is shocked to learn a family member would kill her.

"She was kind, and she had a very good heart. A very good heart," he said.

FOX 4 talked with Hearn’s relatives off camera who declined to speculate on a motive. They chose to release a brief statement saying they truly loved her and that this is a tragedy for their family.

"There are questions we have for ourselves," Jackson said. "What caused her to go that far? She was too good of a woman. I don’t know."

Miles was transported to Dallas Police Headquarters and charged with murder. She does not have a criminal history.

Police have not released any potential motive for the shooting.

Online records show Miles is in the Dallas County Jail on a $750,000 bond.
