Boston crowd restrains carjacking suspect after deadly crash and police chase

A chaotic Mattapan street turned into a grim scene of public intervention after a fatal crash and alleged carjacking left one woman dead and a suspect pinned by bystanders. Boston police said the episode began near 1466 Blue Hill Avenue at about 1:59 p.m. Saturday, after an apparent collision at Blue Hill Avenue and Woodhaven Street.

Investigators identified the suspect as Ibraim Matos, 37, of Hyde Park. Police said Matos got out of the damaged vehicle, ran to a woman waiting at a car wash at 1480 Blue Hill Avenue, pulled her from her car and fled the wrong way down Blue Hill Avenue toward Mattapan Square in the stolen vehicle.

From there, police said, the violence escalated in seconds. Matos drove onto the sidewalk and struck a pedestrian near 1629 Blue Hill Avenue, then crashed into another vehicle at Blue Hill Avenue and Fairhaven Street. He fled again before stopping after hitting an MBTA bus near 1629 Blue Hill Avenue, police said.

Officers arrived to find an unresponsive adult female victim on the ground. She was pronounced dead at the scene, and Boston police said her name had not yet been released. Witnesses described a large crowd gathering around the crashed vehicle as community members and an MBTA bus driver worked to stop Matos from escaping. Several bystanders forcibly removed and restrained him until police took him into custody.

The scene underscored both the desperation and the danger that can follow a fast-moving street crime. People who stepped in to stop Matos were confronting a suspect police say had already triggered multiple collisions, a sidewalk strike and a fatal pedestrian crash. Their intervention may have prevented another escape, but it also showed how quickly ordinary passersby can become the only barrier between a suspect and more harm when emergency response is racing to catch up.

Matos is expected to be arraigned in Dorchester District Court on charges of murder, carjacking, leaving the scene of an accident resulting in death and leaving the scene of an accident resulting in personal injury. Boston police said the Boston Neighborhood Trauma Team is offering free, confidential 24/7 support to those affected as the neighborhood absorbs the shock of a death that unfolded in full public view.
