MATTAPAN — Before Ibraim Matos allegedly carjacked a woman at a Blue Hill Avenue car wash, drove down the sidewalk at speed and killed a pedestrian on Saturday afternoon, he had spent more than 17 years cycling through Boston Municipal Court on charges that — with a handful of exceptions — the Suffolk County District Attorney's office either dropped, diverted, or let walk away with a suspended sentence.

Court records reviewed by Mass Daily News show Matos, 37, of Hyde Park, was the named defendant in fifteen criminal cases in Boston Municipal Court between 2009 and 2023, plus two civil debt-collection matters and now a murder complaint. The records below are drawn entirely from BMC dockets; any criminal cases Matos may have faced in other Massachusetts counties or in federal court would not appear in this review. The criminal charges include two firearm cases, a felony strangulation, a felony assault with a dangerous weapon, repeat domestic-violence offenses, multiple restraining-order violations, multiple threats to commit crime, and a string of motor vehicle infractions.

He has gone on the record using the alias "Ibram" in at least one of those cases. Court entries dating back to 2012 also note that Matos was warned, before guilty pleas, of immigration consequences under M.G.L. c. 278, § 29D — the statutory warning given to non-US-citizen defendants. ICE did not respond to a request from MDN to clarify Matos's immigration status as of publication.

What follows is what the dockets show.

A dangerousness finding in 2011

By February 2011, Matos was already deep in the system. He had been arraigned in 2009 on a threat to commit crime that the Commonwealth would later move to dismiss in 2012. He had been arraigned the same year on a separate A&B and license-suspended docket that closed via fine. He had been arraigned in 2010 on possession of ammunition without an FID card and on malicious destruction of property.

On February 14, 2011, Matos was arraigned again, this time on a fresh A&B, and held without bail under Massachusetts's dangerousness statute, M.G.L. c. 276 § 58A. The order kept him in Suffolk County Jail through three successive pretrial hearings before being lifted at the end of March.

That was the first formal finding by a Massachusetts court that he was a danger to the community.

January 20, 2012: three guilty pleas in one hearing

On January 20, 2012, Judge David B. Poole accepted guilty pleas from Matos on three separate dockets at the same hearing — the 2010 ammunition possession case, the 2010 malicious destruction case, and the 2011 A&B case. The sentence on each was 365 days in the House of Correction, with 53 days to serve, deemed served on credit for pretrial detention.

Matos walked out of the courtroom that day. He has not served another day of incarceration on any conviction in the 14 years since. He would later violate probation on those cases multiple times.

Nine months after that plea hearing, Matos was arrested again, this time on a four-count stack from an October 26, 2012 offense in Boston:

Carrying a firearm without a license (felony, M.G.L. c. 269 § 10(a))
Carrying a loaded firearm without a license (felony, M.G.L. c. 269 § 10(n))
A second possession of ammunition without an FID card
Discharging a firearm within 500 feet of a building

Court records show the charges were transferred to a higher court for prosecution, and the judge ordered Matos to be fitted with GPS monitoring prior to any release. He defaulted on the case for over a year, between January 2013 and May 2014.

Then on April 28, 2015, before Judge Eleanor C. Sinnott, the Suffolk County District Attorney's office filed a nolle prosequi on all four charges. The case ended without a conviction. The docket does not record the office's reasoning.

2016: A&B family or household member, dismissed for lack of prosecution

The next case, in August 2016, charged Matos with assault and battery on a family or household member — Massachusetts's standard misdemeanor-level domestic violence charge. The case was dismissed on January 10, 2017 for lack of prosecution.

2020 to 2022: a felony strangulation, diverted

On November 2, 2020, Boston police arrested Matos on charges that, by Massachusetts measure, should have anchored a serious prosecution:

Strangulation or suffocation (felony, M.G.L. c. 265 § 15D(b))
Violation of an abuse prevention order
A&B on a family or household member

A default warrant issued the next day. Matos remained at large for nearly 17 months and was not before a judge until March 30, 2022. Bail was revoked twice during the pretrial period because of new conduct. On September 28, 2022, all three charges — including the felony strangulation — were dismissed for lack of prosecution. The court ordered the dismissal "upon completion of Pre-Trial Diversion program."

2022 to 2023: three more guilty pleas, all suspended

While the strangulation case was still pending, Matos picked up three new criminal cases:

January 4, 2022: violation of an abuse prevention order
April 18, 2022: threat to commit crime, plus resist arrest (the resist arrest charge was later dropped by the Commonwealth)
December 31, 2022: assault and battery with a dangerous weapon (felony, M.G.L. c. 265 § 15B(b))

All three were filed under M.G.L. c. 276 § 56A as domestic-violence-context cases. On January 19, 2023, Judge Kathleen E. Coffey accepted guilty pleas from Matos on all three at the same hearing. The sentence on each: one year in the House of Correction, suspended. Supervised probation, certified batterer's program, and stay-away orders were entered.

Matos served zero days on any of the three. Probation was terminated on August 29, 2024 with no violation found.

The math

In fifteen criminal cases over fourteen years, Matos was convicted six times — three misdemeanors in 2012 that ran concurrent, and three 2023 charges (including a felony assault with a dangerous weapon) that drew suspended sentences. Total time actually served on conviction sentences: 53 days, all in early 2012.

The Suffolk County District Attorney's office, across four different district attorneys, dropped or diverted his most serious charges: a loaded illegal firearm and discharge case in 2015, a misdemeanor domestic violence case in 2017, and a felony strangulation in 2022. The court entered formal dangerousness or domestic-violence-context findings against him in 2011 and again in both 2022 cases.

Then, Boston police say, on June 20, 2026, Matos crashed his own car at Blue Hill Avenue and Woodhaven Street, ran south to the Fernandez Xpress Car Wash at 1480 Blue Hill Avenue, carjacked a woman waiting in her vehicle, drove the wrong way on the sidewalk at high speed, and struck and killed a woman pedestrian near Fairhaven Street. He came to a stop after crashing into a Route 28 MBTA bus at 1629 Blue Hill Avenue. Bystanders pinned him to the pavement until officers arrived.

Matos is charged with murder, carjacking, and two counts of leaving the scene of an accident.
