MS-13 Member Sentenced to 15 Years for Racketeering in 2010 Murder Case
A 35-year-old member of the notorious MS-13 gang was sentenced to 15 years in federal prison this week for his role in the cold-blooded killing of a 28-year-old man nearly 16 years ago in Chelsea, Massachusetts. Adam Rodriguez, also known as “Pelon,” appeared before Senior U.S. District Judge William G. Young, who handed down the sentence after Rodriguez admitted his guilt last summer to conspiracy to participate in a racketeering enterprise.
The sentencing closes a chapter on a brutal attack that had gone unsolved for over a decade, until a re-examination of evidence by federal investigators and local police tied Rodriguez and other gang members to the December 2010 murder. The case highlights how federal racketeering laws can be used to hold gang participants accountable for long-ago violence and to dismantle organized criminal networks.

MS-13’s Violent Presence in Massachusetts
La Mara Salvatrucha, or MS-13, is a transnational criminal organization that originated in Los Angeles in the 1980s and has since spread across the United States, El Salvador, Guatemala, Honduras, Mexico, and elsewhere. The FBI and Department of Justice have described MS-13 as one of the most dangerous street gangs, with tens of thousands of members worldwide. In Massachusetts, the gang operates through local cliques that enforce strict rules of loyalty and violence.
According to the federal release, MS-13 members are required to commit acts of violence — particularly against rival gang members — to maintain their standing within the gang. They are expected to kill informants, defend fellow members in attacks, and carry out orders from gang leaders. This culture of violence is what federal prosecutors say drove Rodriguez and his co-defendants to plan and execute the 2010 murder.
The gang’s influence in the Boston area has been the target of multiple federal investigations, and the successful prosecution of Rodriguez and his associates is part of a broader effort to disrupt MS-13’s operations in New England.
The 2010 Murder: How the Attack Unfolded
On the evening of December 18, 2010, a 28-year-old man was found suffering from multiple stab wounds near the Fifth Street on-ramp to Route 1 in Chelsea. Responders had been alerted by a 911 call, and they discovered the victim with approximately 10 stab wounds to his chest and back, along with injuries to his head. He was rushed to a hospital but died from his wounds.
For years, the case went cold. But a recent re-examination of evidence collected at the time identified several members of MS-13 as the perpetrators. According to prosecutors, the murder was the result of a conspiracy: in the week leading up to the killing, Rodriguez, co-defendant Jose Vazquez, and other MS-13 members had plotted to kill the victim because they believed he belonged to a rival gang.
On the day of the murder, co-defendant William Pineda Portillo picked up Rodriguez, Vazquez, other gang members, and the victim in Allston and drove the group to Chelsea. Once there, the gang members led the victim to a secluded area under the highway overpass. In that isolated spot, one MS-13 member struck the victim in the head with a rock, another stabbed him with a machete, and Vazquez stabbed him with a knife. Crucially, Vazquez’s palm print was later identified on the handle of a silver kitchen knife recovered at the scene. The victim’s blood was also found on the blade.
This coordinated attack, prosecutors said, was a textbook MS-13 execution — a show of force designed to punish a perceived rival and boost the gang’s reputation.
The Long Investigation and Racketeering Charges
The break in the case came when investigators, including the FBI, Homeland Security Investigations, and state and local police, took a fresh look at the physical evidence. Advances in forensic analysis and a re-interview of witnesses allowed them to connect Vazquez, Rodriguez, and others to the crime.
Further incriminating evidence emerged from an undercover recording of an MS-13 meeting held on January 27, 2011 — about six weeks after the murder. At that meeting, Rodriguez was heard acknowledging his role in the killing. The recording also captured other gang members disciplining him for leaving Massachusetts after the murder without the gang’s permission, underscoring the rigid internal control MS-13 exerts over its members.
In November 2023, a federal grand jury returned an indictment charging Rodriguez, Vazquez, and Pineda Portillo with conspiracy to participate in a racketeering enterprise. Racketeering charges, often brought under the Racketeer Influenced and Corrupt Organizations (RICO) Act, allow prosecutors to link multiple criminal acts — including murder, drug trafficking, and other violent crimes — to a criminal organization. For gang cases, this is a powerful tool because it treats the gang itself as an illegal enterprise and holds its members accountable for the full range of their criminal activities.
Rodriguez chose to plead guilty in July 2024, admitting to the racketeering conspiracy. By doing so, he avoided a trial and accepted responsibility for his role in the murder, though he was not specifically charged with murder in the indictment; the murder was part of the broader pattern of racketeering activity.
Guilty Plea and Sentencing
At his sentencing on May 6, 2026, Judge Young imposed a 15-year prison term, to be followed by three years of supervised release. The sentence reflected the seriousness of the offense, Rodriguez’s cooperation and acceptance of responsibility, and the need to protect the public. Under federal law, Rodriguez will serve at least 85% of his prison term before being eligible for good-time credit.
Rodriguez’s guilty plea and sentence are the culmination of years of investigation by multiple law enforcement agencies. It also illustrates how federal prosecutors can pursue justice even in cases where the crime occurred more than a decade ago, as long as the statute of limitations has not expired. For many violent crimes, including murder, there is no statute of limitations at the federal level.
The sentencing hearing also offered a measure of closure to the victim’s family, who had waited nearly 16 years for accountability.
Co-Defendants’ Sentences
Rodriguez’s two co-defendants have already been sentenced. In July 2025, Jose Vazquez, also known as “Cholo” or “Little Crazy,” received a 25-year prison term to be followed by five years of supervised release. Vazquez was already serving a 212-month sentence (more than 17 years) for a separate 2018 federal conviction for conspiracy to participate in a racketeering enterprise. His new sentence runs consecutively, meaning he will spend a total of 37 years behind bars for his crimes.
William Pineda Portillo, an illegal alien from El Salvador, was also sentenced in July 2025 to 16 years in prison. Upon completion of his sentence, he will be subject to deportation proceedings. Pineda Portillo’s role was to transport the group to the murder scene — an act that, under federal racketeering law, made him equally liable for the resulting death.
These sentences underscore the heavy penalties that can result from gang involvement, even for actions that might appear secondary. Under RICO, every participant in a criminal enterprise can be held accountable for all reasonably foreseeable acts committed by their co-conspirators.
Legal Context: Racketeering and Gang Prosecutions
Racketeering charges are frequently used against organized crime groups because they provide a framework for prosecuting the entire criminal enterprise, rather than just individual crimes. To convict someone of racketeering, prosecutors must prove that the defendant was associated with an enterprise that engaged in a pattern of criminal activity, and that the defendant participated in that enterprise through at least two predicate acts.
In this case, the murder of the 28-year-old man was just one of many violent acts that prosecutors say MS-13 committed to maintain its grip. By pleading guilty to the racketeering conspiracy, Rodriguez admitted that he was part of the gang’s criminal enterprise and that the murder was committed in furtherance of that enterprise.
This approach has been central to the Justice Department’s strategy in combating MS-13. Over the past decade, federal prosecutors have secured hundreds of racketeering convictions against MS-13 members across the country, often relying on evidence gathered through wiretaps, undercover recordings, and forensic re-examinations of cold cases.
Public Safety and the Federal Response
The case is part of Operation Take Back America, a nationwide initiative that coordinates the resources of the Department of Justice, including its Organized Crime Drug Enforcement Task Forces (OCDETF) and Project Safe Neighborhood (PSN) programs. The operation aims to “repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime,” according to DOJ statements.
While such language is politically charged, the operational goal is straightforward: leverage federal resources to dismantle gangs and drug trafficking networks that cross state and national borders. Because MS-13 operates both locally in cities like Chelsea and globally across Central America, it falls squarely within the scope of such federal initiatives.
United States Attorney Leah B. Foley; Ted E. Docks, Special Agent in Charge of the FBI Boston Division; and other federal, state, and local officials announced the sentencing. The cooperative effort involved Homeland Security Investigations, the Massachusetts State Police, the Somerville and Chelsea police departments, the Bureau of Alcohol, Tobacco, Firearms and Explosives, Customs and Border Protection, and Citizenship and Immigration Services — a broad coalition that reflects the seriousness with which authorities view MS-13’s threat.
What Remains Unclear
While the sentencings bring legal resolution, several questions remain publicly unanswered. Authorities have not released the full identity of the victim beyond his age, nor have they detailed why the gang specifically believed he was a member of a rival group. The federal release does not indicate whether the victim was indeed affiliated with any gang, leaving open the possibility that he may have been targeted by mistake or based on a false rumor.
Additionally, the prosecution did not publicly name every MS-13 member present during the attack. The indictment focused on the three defendants, but the original undercover recording and witness accounts suggest there were additional gang members involved. Whether they will face charges remains unknown.
The long delay between the crime and the indictments also raises questions about the initial investigation and why key forensic evidence — such as the palm print on the knife — did not lead to arrests sooner. Authorities have not explained this publicly, though cold-case reviews often become possible only when technology advances or witnesses become willing to cooperate years later.
Finally, the case illustrates the challenges of prosecuting gang violence in immigrant communities, where fear of retaliation, language barriers, and distrust of law enforcement can hinder investigations. While these factors are not unique to Chelsea, they may have contributed to the time it took to solve the case.
Frequently Asked Questions
What was Adam Rodriguez convicted of?
Rodriguez pleaded guilty to conspiracy to participate in a racketeering enterprise, which is a federal felony. He admitted his involvement in the MS-13 gang and his role in the 2010 murder as part of that criminal enterprise.
Did Rodriguez directly stab the victim?
According to the federal release, Rodriguez was not the one who stabbed the victim, but he conspired in the murder and was present during the attack. Under federal racketeering law, his participation in the conspiracy makes him criminally liable for the killing.
Why did it take so long to bring charges?
The case went cold for years. A recent re-examination of evidence — including forensic analysis and the undercover recording — eventually identified the suspects. Such delays are common in older cases where physical evidence requires new analysis or where witnesses come forward later.
What does a racketeering charge mean?
Racketeering charges are used to prosecute members of an ongoing criminal organization for multiple crimes that are part of a pattern of illegal activity. It allows prosecutors to link a single defendant to the larger gang’s actions, even if they did not personally commit every offense.
Will there be any further prosecutions in this case?
Unknown. The federal release did not indicate whether other individuals involved will be charged. Investigations often continue after the conviction of the main participants.
