D. Mass.Jun 30, 2025Background
- Ralph DeLeo was on supervised release following concurrent federal sentences for drug and racketeering offenses from the Eastern District of Arkansas and District of Massachusetts.
- In May 2025, the FBI began investigating DeLeo after a confidential informant reported DeLeo was seeking personal information about federal officials involved in his prior cases, allegedly to harm them.
- A search of DeLeo’s residence uncovered documents with officials’ personal information, marijuana, burglary tools, a note about silicone masks, and his cell phone.
- Digital evidence revealed DeLeo communicated with known felons and conducted extensive internet searches related to federal officials and surveillance equipment.
- The U.S. Probation Department petitioned to revoke DeLeo’s supervised release for three violations: making false statements to federal officers, contacting known felons, and possessing controlled substances.
- The court consolidated both district cases for a preliminary/detention hearing to decide probable cause for violations and DeLeo's pre-hearing detention status.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Probable cause for violations of supervised release | Evidence supports probable cause for all violations | No probable cause; information from unreliable source | Probable cause exists for all alleged violations |
| Risk of flight or danger to community | DeLeo’s history, conduct, and planning show risk | Not likely to flee or endanger others; poor health | DeLeo poses risk of flight and danger; detention warranted |
| Relevance of defendant’s medical condition | Not relevant under bail statute at this stage | Health prevents risk/escape; requires medical care | Health issues do not outweigh risk of flight/danger |
| Legitimacy of information search | Search intent was for illegal purposes | Information related to legal challenge of conviction | Defense argument insufficient to counter risk evidence |
