A Department of Homeland Security employee out walking her dog was brutally murdered in Georgia — by a man naturalized under former President Joe Biden, Homeland Security Secretary Markwayne Mullin said Wednesday.
Mullin said that Olaolukitan Adon Abel, the 26-year-old man suspected of killing 40-year-old DHS employee Lauren Bullis in Dekalb County was naturalized by the Biden Administration in 2022. Abel was born in the United Kingdom and has an extensive criminal history including convictions for sexual battery, battery against a police officer, obstruction, and assault with a deadly weapon, and vandalism, Mullin said.
“He has also been arrested for the murder of an unidentified woman whom he reportedly shot outside a Checkers, before randomly shooting a homeless man multiple times outside a Kroger in Brookhaven,” Mullin said. “These acts of pure evil have devastated our Department and my prayers are with the families of the victims.”
On Monday, a DHS employee, Lauren Bullis, was brutally shot and stabbed to death by Olaolukitan Adon Abel, a 26-year-old, born in the United Kingdom, who was naturalized by the Biden Administration in 2022.

Abel has been charged with two counts of murder and aggravated assault, in addition to multiple gun charges.
Police have described the attacks as random, with the first beginning at 12:52 a.m. Monday morning and the second at around 2:00 a.m. Bullis was attacked at around 6:50 a.m. and died after being stabbed and shot. Her dog, Sancho, has been missing since the attack, according to local reporting.
Mullin said that the Trump administration was working to ensure that only those with good character could attain American citizenship.
“Since President Trump took office, [U.S.] Citizenship and Immigration Services] has implemented measures to ensure individuals with criminal histories and who otherwise lack good moral character do not attain citizenship,” Mullin said.
In a later statement, Homeland Security emphasized the fact that the suspect was “NATURALIZED BY THE BIDEN ADMINISTRATION” and said the department’s “prayers are with the families of the victims during this tragic time.”

Bullis worked in the office of Inspector General for the Department of Homeland Security as an auditor and as a team leader in the Office of Innovation.
“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. We strongly condemn this act of violence,” the department said. “We will cooperate with the ongoing investigation but will not comment further on the suspect or the nature of the case.”
Her family said that she “deeply loved her family and found joy in running, reading, and traveling,” and that her “generosity touched everyone surrounding her.
