A Department of Homeland Security employee was murdered by a convicted felon immigrant who was naturalized under the Biden administration during a bloody killing spree in Georgia early this week, officials said Wednesday.
Lauren Bullis, who worked as an auditor for DHS’s Office of Inspector General, was shot and stabbed in Atlanta when 26-year-old Olaolukitan Adon-Abel allegedly went on his deadly rampage on Monday morning.
Bullis, a 40-year-old auditor for the DHS, had taken her dog out for a stroll about 7 a.m. when she was targeted as part of three random attacks carried out by the madman across the Atlanta area, cops allege.

Adon-Abel’s alleged rampage also killed another woman outside a Checkers restaurant and critically injured a homeless man who was sleeping outside a Kroger store, according to authorities.
DHS Secretary Markwayne Mullin has since revealed the alleged perp, who was born in the UK and became a naturalized US citizen in 2022 under Biden, already had a lengthy rap sheet prior to this week’s bloodshed.
“He possesses a prior criminal record that includes convictions for sexual battery, battery against a police officer, obstruction, and assault with a deadly weapon, vandalism and now stands accused of murdering [DHS] employee Lauren Bullis by shooting and stabbing her while she walked her dog,” he said.

“These acts of pure evil have devastated our department and my prayers are with the families of the victim.”
The deadly spree started outside a Checkers restaurant on Wesley Chapel Road in Dekalb County when the suspect gunned down the first victim around 1 a.m, cops said.
The woman, identified as 31-year-old Prianna Weathers, died at a nearby hospital.
Adon-Abel, who lives in Atlanta, then drove roughly 16 miles before he allegedly opened fire on a sleeping 49-year-old homeless man outside the Kroger grocery store in Brookhaven at about 2 a.m.
His alleged spree ended several hours later when he shot and stabbed Bullis some 15 miles away, according to authorities.
A neighbor who ran out of her house after hearing the gunfire told 11 Alive it appeared as though the suspect was trying to sexually assault Bullis at the time.

“It is apparent to us that this was a completely random attack,” Brookhaven Police Chief Brandon Gurley said.
Adon-Abel was nabbed a short time later and slapped with a slew of charges, including malice murder, aggravated assault and possession of a firearm during the commission of a felony.
It wasn’t immediately clear if Adon-Abel’s prior convictions predated his arrival in the US.
His criminal record includes a conviction from October 2024 in San Diego, California where he pleaded guilty to felony assault with a deadly weapon other than a firearm on a police officer or firefighter.

Exact details surrounding that arrest weren’t immediately available but he was sentenced to probation.
Just months later, he was then nabbed for groping four women in Savannah, Georgia, in a matter of hours.
At least one of the women Adon-Abel approached in that April 2025 incident had been walking her dogs at the time, records show.
He was sentenced to 120 days in jail, three years’ probation, and was ordered to undergo a mental health evaluation following that saga.
In the wake of his latest arrest in Atlanta, the Homeland Security boss hailed the Trump administration’s efforts in clamping down on giving citizenship to violent offenders.
Bullis’ dog, Sancho, has been missing since the murder.
“Since President Trump took office, @USCIS has implemented measures to ensure individuals with criminal histories and who otherwise lack good moral character do not attain citizenship,” Mullin said.
Meanwhile, authorities still haven’t yet determined a motive for the latest crime spree.
Homeland Security refused to comment further about the suspect but said the federal agency strongly condemned the slayings.
“We are deeply saddened to confirm that Lauren Bullis, a beloved member of the Department of Homeland Security Office of Inspector General team has tragically passed away,” a spokesperson said.
“She was a respected colleague whose contributions and presence will be greatly missed. We extend our heartfelt condolences to her family and friends, as well as to the families, friends, and communities of the additional victims.”
Her family issued a statement, too, describing Bullis as a “selfless, kind and compassionate” woman.
“She deeply loved her family and found joy in running, reading and traveling,” the statement said.
“Her warmth and generosity touched everyone surrounding her.”
