Authorities in a progressive suburb of Washington, DC, repeatedly urged prosecutors to detain a serial criminal, an undocumented immigrant, whom they deemed a significant threat to public safety—long before he allegedly fatally stabbed a local mother at a bus stop.

Police in Fairfax, Virginia, had raised concerns about Abdul Jalloh—who has faced over 30 arrests—as early as May 2025. According to a revealing report by WJLA-News on Wednesday, these concerns were communicated through emails to the Fairfax County Commonwealth’s Attorney.

In November 2025, a police major reached out to the prosecutor’s office, emphasizing Jalloh’s release. “I wanted to bring Mr. Jalloh’s release to your attention,” the email stated, highlighting Jalloh as a repeat and violent offender previously discussed during a meeting. The major sought clarification on why Jalloh was released so quickly and questioned if a previously suspended five-year sentence had been enforced by the prosecutor’s office.

The major further expressed in the email, “Based on numerous encounters with him, it’s not a matter of if he will injure someone again, but when. My duty to ensure public safety compels me to inquire about his current status.”

These warnings came after an earlier email in August 2025 from another senior officer, who pointed out that Jalloh had been involved in over 100 incidents with the Fairfax County Police Department, according to WJLA.

That warning followed an August 2025 email from another high-ranking cop, who noted that Jalloh had “over 100 involvements” with the Fairfax County Police Department, WJLA reported.

“JALLOH’s offenses began with domestic violence incidents and escalated to assaulting other victims and threats with weapons (knives),” the message said.

“He has been involved in multiple stabbing incidents with victims identifying him as the offender in these cases,” the email said.

“This year JALLOH has been the offender in a malicious wounding where he stabbed a man in May 2025, in which he received a bond on July 31, 2025 — three weeks later, this incident occurred where he assaulted an older male and stomped his head into the ground.”

Jalloh’s rap sheet in the county dates to 2014, when he was charged with assaulting a family member — the first of dozens of busts on drug, larceny, trespassing, malicious wounding and rape charges.

The US Department of Homeland Security, which said it lodged an immigration retainer for Jalloh as early as 2020, slammed “Virginia’s sanctuary politicians.”

It’s not clear when Jalloh was last released from jail.

His latest alleged crime came on Feb. 23, when police said he “hacked” 41-year-old mom Stephanie Minter to death at a Fairfax County bus stop — which finally got him locked up without bail.

Fairfax County says it is not a sanctuary jurisdiction, but top Republicans on the House Judiciary Committee slammed Commonwealth’s Attorney Steve Descano and Sheriff Stacey Kincaid for failing to cooperate with ICE on the arrest of illegal migrants.

Federal immigration officials lodged a detainer against Jalloh in 2020, but he was never held by local authorities to be turned over the the feds.

In fact, in more than a dozen of Jalloh’s prior arrests, prosecutors listed the cases as “nolle prosequi” — which translates to unwilling to prosecute.

A spokesperson for Descano told The Post this week that the cases remain open to future prosecution, but said Jalloh’s penchant for targeting unreliable homeless victims made it hard to pursue the cases.

“Unfortunately, the defendant in this case also had a history of selecting victims with no fixed address – some of the most vulnerable members of our community,” office rep Laura Birnbaum said.

In several cases, she said prosecutors “were unable to move forward with prosecution because we did not have victims’ participation or presence at court hearings, and successful prosecution would have depended on victim testimony.”

In an email Wednesday responding to the WJLA report, Birnbaum said, “Our office was aware of Jalloh’s criminal history and shared police concerns about potential future dangerousness – that is why our Chief Deputy Commonwealth’s Attorney personally handled these cases.

“Prosecutors will often explore many different pathways to successful prosecution, but at the end of the day our decisions are constrained by what testimony is available and what is legally permissible and practicable in Fairfax courts,” she said.
