JONESBORO — Aliyah Patton, 23, of Jonesboro, was arrested Wednesday on suspicion of first-degree murder in the death of her infant daughter on Sept. 27, 2020, according to Jonesboro police.

Officers responded after an unresponsive infant was admitted to the Emergency Room of St. Bernards Medical Center. Detectives were called in to begin their investigation.

An autopsy was performed by the Arkansas State Crime Lab, and the results were obtained by JPD on Monday.

The child was born prematurely in June 2020, police said.

Patton pleaded guilty in February to aggravated assault and endangering the welfare of a minor in which she was accused of trying to run over a woman and her 2-year-old child on Oct. 1, 2020, at the intersection of Vine Street and Cherry Avenue.

The victim said she and the suspect began an argument at the Walmart on Highland Drive and it continued until they got to the Vine and Cherry intersection. The victim then got out of the car with her daughter. She said that is when Patton tried to run her and her daughter over, according to a probable cause affidavit.

Patton pleaded guilty on Feb. 8 and received two years of probation, according to court documents.
