William Langrum

A suspect who was captured after committing an aggravated robbery in Oak Lawn last week is now charged with capital murder in the stabbing death of a Lake Highlands woman, according to Dallas police.

William Langrum, 27, was arrested Sept. 21 following a chase that began in the 2800 block of Douglas Avenue, when undercover officers observed Langrum and another suspect steal a bag of clothes from a victim at knifepoint. After eluding officers in their vehicle and on foot, Langrum and his accomplice, 18-year-old Jeremy Francis, were apprehended in the 7100 block of Lemmon Avenue.

Police say evidence recovered at the scene of the Douglas Avenue robbery linked Langrum to the murder of Shearl Bennett, who’d been fatally stabbed outside her Lake Highlands home about an hour before. Bennett was returning home from church at about 10:45 p.m. Sept. 21 when she was stabbed outside her car in the 9800 block of Royal Lane.

On Monday, detectives charged Langrum with capital murder in Bennett’s death. Both Langrum and Bennett also face charges of aggravated robbery and evading arrest in connection with the Douglas Avenue robbery.

“It was a good catch over in Oak Lawn,” said Laura Martin, DPD’s LGBT liaison officer. “We’ve had officers over there on special assignment a lot because we’ve been having issues with robberies.”
