Nearly 1 in 12 Chicago Defendants on Ankle Monitors Have Vanished

Of the 3,048 criminal defendants currently released pre-trial on ankle monitors in Chicago, 246 of them are gone. They're not wearing their monitors. Nobody knows where they are.

That's nearly one in twelve people the system believed it was tracking.

Data from the Circuit Clerk of Cook County shows the 246 missing defendants include some charged with serious violent offenses — among them 21 charged with murder, 13 with attempted murder, 103 with sexual assault, and 173 with aggravated battery.

Cook County Chief Judge Charles Beach acknowledged law enforcement is actively searching for the missing defendants but tried to add context.

"It doesn't mean they're out committing crimes necessarily," Beach said. "Some might be. But they're actively being searched for right now by law enforcement."

That reassurance is harder to hear given what's already happened with people who were tracked and still allegedly committed violent crimes while wearing their monitors.

The Cases That Defined the Debate

Alphanso Talley was on electronic monitoring when he allegedly shot and killed Chicago Police Officer John Bartholomew. Talley had received his first ankle monitor in December 2025. It logged two violations within three days in early March. He remains charged with murder. The case became a flashpoint in the ongoing debate about pre-trial release policy in Illinois — a debate that had already been running hot since the state moved to cashless bail.

In November 2025, Lawrence Reed — who has been arrested at least 13 times by Chicago police since 2017 — allegedly set a woman on fire on a Chicago Blue Line train while on an ankle monitor, yelling "burn b----." He had been released pre-trial with the monitor against prosecutors' explicit objections after being charged with aggravated battery in August 2025. The case illustrated what critics say is one of the program's core failures: that monitors can be ordered even when the people most familiar with a defendant's history are actively arguing against release.

In December 2025, Marlon Miller allegedly attacked three women in the downtown area — all while wearing an ankle monitor.

How Electronic Monitoring Is Supposed to Work

The ankle monitor program is designed as an alternative to pre-trial detention — a way to allow defendants to maintain employment, family connections, and housing while awaiting trial, without the presumption-of-innocence problem that comes with locking someone up before they've been convicted of anything.

Under Illinois' SAFE-T Act, which eliminated cash bail in 2023, judges determine pre-trial release conditions based on risk assessments that weigh factors including the seriousness of the charge, criminal history, and ties to the community. Electronic monitoring is one of the tools available to supervise defendants released while their cases proceed.

When the system works as intended, a monitor creates accountability — it logs a defendant's location continuously, generates alerts when they leave designated areas or violate curfew, and provides law enforcement with a record if something goes wrong. Cook County's program is administered through the Sheriff's Office, which is responsible for responding to violations.

The problem is that violations require a response, and responses require resources. When monitors log infractions — as Talley's did twice in three days — someone has to act on that information quickly enough to matter. That chain of accountability is what critics say has repeatedly broken down.

The Larger System Debate

Beach defended the overall program, pointing out that violent crimes were also committed by defendants released on monetary bail before Illinois moved to cashless bail. "That is the nature of a system that is designed with the presumption of innocence," he said.

That argument may be legally sound. The SAFE-T Act's supporters have consistently pointed out that the old cash bail system had its own serious failures — that it detained poor defendants who posed little risk while allowing wealthier defendants to buy their way out regardless of danger level. The move to risk-based assessment was intended to be a more rational system, not a more lenient one.

But 246 people charged with violent offenses who have removed their monitors and cannot be located is not a statistic that fits neatly into either side of that argument. It is its own problem — a gap between what the system promises and what it currently delivers.

It doesn't make it easier to explain to the families of victims. And it will be harder still to explain if any of the 246 are found only after something else goes wrong.
