The suspect accused of killing a Homeland Security employee and two others in an Atlanta-area shooting spree has died in jail.
Olaolukitan Adon Abel, 26, was found in his cell unresponsive, according to the DeKalb County Sheriff’s Office. Lifesaving measures were performed, officials said, but he was later pronounced dead.
The official cause of his death has not been determined, but officials do not suspect foul play, the sheriff’s office said.
Abel has been accused of killing Prianna Weathers, 31, and DHS auditor Lauren Bullis, 40, in last week’s attack.
He also allegedly attacked Tony Mathews, a 49-year-old homeless man, who was injured and then later died Sunday.
According to investigators, Abel traveled about five miles from his home and shot and killed Weathers outside a fast-food restaurant at 12:50 a.m.
Two hours later, Abel allegedly shot Mathews outside a supermarket in Brookhaven, about 12 miles from the first attack.
The third victim, Bullis, was walking her dog near Abel’s home when she was stabbed and shot. She was found dead around 7 a.m.
It’s unclear whether Abel knew any of the victims. Authorities had still been working to determine a motive in the attack.
Abel was originally from the United Kingdom and became an American citizen in 2022 while serving in the U.S. Navy and stationed in the San Diego area.
He was facing charges in Georgia state court with two counts of malice murder, aggravated assault, and gun offenses. He was also facing a federal firearms charge.
Additionally, another man accused of buying the gun for Abel that was used in the shooting also faces a federal firearms charge. A prior felony conviction didn’t allow Abel to legally purchase a gun himself.
Abel has a lengthy criminal record that includes convictions for sexual battery, battery against a police officer, obstruction, assault with a deadly weapon, and vandalism, according to Homeland Security.
The case has renewed scrutiny over federal vetting procedures. Homeland Security Secretary Markwayne Mullin said he was naturalized under the Biden administration.
In December 2025, USCIS created a new vetting center to beef up the screening and vetting of immigration applicants to root out terrorists, criminal aliens, and other threats to public safety.
