BOCA RATON, FL (Boca Post) (Copyright © 2025) — A Boca Raton man accused of trafficking fentanyl is sitting in the Palm Beach County Jail with no bond after a judge ordered pretrial detention, court records show.

Alexander Zheleznyak, 19, was arrested Dec. 11 by the Palm Beach County Sheriff’s Office and booked into the Main Detention Center. He’s charged with two counts of trafficking in fentanyl or fentanyl analogues, each at the four-grams-or-more level, under Florida Statute 893.135(1)(c)1a.

By the time the court file updated, the key parts were already in place: probable cause found, a state motion for pretrial detention granted, and bond set at none. That’s the posture right now. He remains in custody as of Friday.

Jail and court records list an East University Drive address in Boca Raton. It matches university-affiliated housing at Florida Atlantic University. What the file doesn’t say—at least not in anything public yet—is whether the alleged offense happened on campus or off it. No location details in the docket entries you can actually read.

The probable cause affidavit isn’t available in the public file at this point. The docket indicates the arrest record and a criminal probable cause affidavit were received in redacted form, and it also references a judge’s probable cause affidavit entered under an administrative order. Still, the judge’s probable-cause finding is reflected in the record, and the detention order followed.

Fentanyl trafficking at the four-gram threshold is treated as a first-degree felony in Florida. It’s also the kind of charge where prosecutors can ask for detention without bond, and judges can grant it if they find the legal standard is met.

Zheleznyak had private counsel at first appearance, according to the docket.

The case is assigned in circuit court and is set to move through the usual early schedule, with additional dates listed for January and an initial case conference in early February.

No plea has been entered in the publicly visible record. The charges are allegations and have not been proven in court.

For now, it’s simple: a young defendant, a serious fentanyl trafficking case, and a judge saying no bond. The rest of the story will be in whatever records come next.
