A Lynn jury on Friday acquitted 18-year-old Iram Allen of second-degree murder in the 2023 stabbing death of 17-year-old Daniel Marquez Santeliz, closing a case that has weighed on the city since a fatal clash inside a Freeman Square convenience store. The not-guilty verdict came within hours of deliberations on the ninth day of the trial.
Jurors reached their decision after hearing nine days of testimony in Essex Superior Court. Before the trial began, the judge restricted what prosecutors could say about gang ties, blocking any explicit link between Allen and the Trinitarios in front of the jury, a limit that shaped how the state framed motive and context, as reported by MassLive.
What Happened in 2023
The stabbing unfolded in August 2023 inside the Alpha Convenience Store at 1 Freeman Square in Lynn. According to a news release from the Essex County District Attorney's Office, Marquez Santeliz was rushed to Salem Hospital, where he was later pronounced dead.
Allen was 15 at the time of the incident. He was charged in connection with the killing and prosecuted as an adult under Massachusetts rules that require anyone 14 or older who is charged with first or second-degree murder to be tried in adult court, as detailed by the Boston Globe.
How the Trial Unfolded
At trial, both prosecutors and Allen’s defense team agreed on the rough outline of what happened. They told jurors that Marquez Santeliz shoved Allen, that Allen pulled a kitchen knife from his waistband, and that he stabbed Marquez Santeliz, with the blade piercing the bottom of the victim’s heart, according to MassLive.
Prosecutors argued that sequence of events amounted to second-degree murder. Defense attorneys countered that the killing stemmed from a fast-moving, chaotic fight and that the state had not proven the kind of intent required for a second-degree murder conviction.
Federal Probe and Local Impact
Months after the stabbing, federal authorities announced a sweeping RICO case in February 2025 targeting alleged Trinitarios leaders and members. The investigation grew out of a string of Lynn homicides and violent incidents in 2023, and the operation was described as a major blow to the gang’s leadership by the U.S. Attorney’s Office in Massachusetts.
That federal case kept wider concerns about gang activity and youth violence in the spotlight even as local prosecutors pursued the specific murder charge against Allen in state court.
What the Verdict Means
The jury’s decision clears Allen of the second-degree murder charge and ends the criminal case against him on that count. Because he was prosecuted as an adult under state law, the case played out in Superior Court, a process governed by Massachusetts rules that require adult prosecution for suspects 14 and older who are charged with first or second-degree murder, as reported by the Boston Globe.
The verdict leaves family members, neighbors, and city officials still grappling with the loss of Marquez Santeliz and the broader questions the case raised about teen violence and gang influence in Lynn. Local leaders and law enforcement say those deeper problems will not disappear just because this particular case has now run its course in court.
