MANSFIELD — A 26-year-old Mansfield man was arrested Tuesday after police executing a search warrant on Oakland Street seized cocaine, nearly $49,000 in cash, and firearms.
According to Mansfield Police Chief Ronald Sellon, the arrest followed a lengthy multi-agency investigation led by the Mansfield Police Detective Division, with assistance from detectives from the Raynham and Seekonk police departments and agents from the U.S. Drug Enforcement Administration’s Worcester office.
On Tuesday, May 26, 2026, Mansfield police detectives and members of the Northern Bristol County Drug Task Force searched a suspect — identified as Jonathan Mejia, 26, of Mansfield — his apartment and a rental car on Oakland Street after securing a warrant.
During the execution of the search warrant, detectives seized 63 grams of a white powdery substance believed to be cocaine, $48,961 in cash, two handguns and three high-capacity magazines, Chief Sellon said.
Jonathan Mejia, 26, of Mansfield, was arrested and charged with the following:
- Cocaine trafficking
- Possession of a large-capacity firearm (three counts)
- Possession of a firearm while committing (or attempting to commit) a felony (cocaine trafficking)
- Improper storage of a large-capacity firearm
“This arrest was due to an incredibly thorough and professionally conducted investigation led by Mansfield Police Detectives Anthony Lattanzio, Patrick Pennie, Chris Walsh and Matthew Souza,” Chief Sellon said. “Investigations like this wouldn’t be possible without cooperation from our partners in law enforcement, including Raynham Police Detectives Patrick Leahy and Jared Turkington, Seekonk Police Sergeant Adam Laprade, and agents from the DEA’s Worcester office. This case took a lot of guns and drugs off our streets, and all of our communities are safer because this investigation was so successful.”
Bristol County Sheriff Paul Heroux notes that serious drug charges are often accompanied by firearms charges of inmates awaiting trial in jail. “Although society has decriminalized marijuana, there is still a nexus between other illicit drugs and unregistered firearms,” said Sheriff Heroux. He continued, “All defendants should be presumed innocent until proven guilty in a court of law.”
