Dunwoody police say they don’t know what drove a 27-year-old man to beat and stab his 15-year-old sister to death outside their apartment Monday afternoon.
Gavin Denzell Henderson was arrested on charges of felony murder, aggravated assault with the intent to murder and cruelty to children in the first degree in the death of his sister, Keaira Henderson, after he called police to turn himself in.
A neighbor called 911 to report someone was beating the girl in front of the Lacota Apartments in the 6600 block of Peachtree Industrial Boulevard around 3:20 p.m. Monday, Dunwoody police Sgt. Robert Parsons said.
The caller said the man and the girl were in a heated argument and the teen went door to door looking for someone to help, Channel 2 Action News reported.
Officers responded just minutes after the call, but Keaira Henderson was dead in the breezeway by the time they got there. She was stabbed multiple times, according to police.
Her older brother was arrested a short time later outside a discount store in the 6800 block of Peachtree Industrial Boulevard.
The manager of the store told Channel 2 they called police at Gavin Henderson’s request, after he walked into the store carrying a knife and covered in blood. Police believe the knife was the murder weapon.
“He just told me, ‘Can you call the cops?’ I said, ‘Why?’ He said, ‘There’s been an accident,’” Shehab Faisal said. “He’s showing me blood on his hands and his T-shirt.”
When police arrived just after 3:30 p.m., Faisal said Henderson walked out of the store and surrendered. He was taken into custody without incident and the knife was recovered, according to police.
“The motive for this attack is still under investigation,” Parsons said.
No further details are expected to be released as the DeKalb County District Attorney’s Office is preparing for prosecution.
