A Union County grand jury has returned a four-count indictment against the former fugitive charged with beating a man to death in Plainfield in 2007, acting Union County Prosecutor Grace H. Park announced Friday.
Welder “Dario” Morente Dubon, 31, formerly a resident of Plainfield, is charged with murder, two related weapons offenses, and hindering apprehension. He was located and arrested by FBI agents and members of the Guatemalan Police of the Transnational Anti-Gang Unit in Guatemala in October 2016 following a nearly decade-long search involving a dozen municipal, county, state, and federal law enforcement agencies.
On March 29, 2007, Dubon was working at a tire shop on the 1600 block of South Second Street in Plainfield when 23-year-old Joseph Tremarco of the Millington section of Long Hill, the owner of a local scrap metal salvage business, arrived there to conduct a transaction with him, according to the investigation.
Following an argument, Dubon allegedly beat Tremarco to death with a blunt instrument, moved the victim’s body into his work vehicle, and parked it on a residential street in neighboring North Plainfield before fleeing the area.
Tremarco’s body was discovered the next day. A warrant was subsequently issued for Dubon’s arrest, but by then, investigators believe that he had already traveled to Central America.
The extensive investigation and search for Dubon ultimately grew to also leverage the resources of the U.S. Marshals Service, the FBI’s Newark office, the Drug Enforcement Administration, the U.S. State Department, U.S. Homeland Security Investigations, U.S. Attorney’s Office for the District of New Jersey, New Jersey State Police, Union County Sheriff’s Office, Plainfield Police Division, North Plainfield Police Department, Long Hill Police Department, and Keyport Police Department, in addition to the Diplomatic Security Service (DSS) and Guatemalan Policia Nacional Civil (Guatemalan National Police).
In September 2009, the case was profiled on the television program “America’s Most Wanted,” and in October 2011, a federal arrest warrant was issued for Dubon in U.S. District Court, charging him with unlawful flight to avoid prosecution. The New Jersey State Police also added Dubon to its 12 Most Wanted list of fugitives.
Dubon was extradited to New Jersey earlier this year. Anyone with information about this matter, or anyone who may have come into contact with Dubon since March 29, 2007, still is being urged to contact Prosecutor’s Office Detective Danika Ramos at 908-451-7739.
Convictions on first-degree murder charges are commonly punishable by 30 years to life in state prison.
These criminal charges are mere accusations. Each defendant is presumed innocent until proven guilty in a court of law.
