DA Tucker Releases Statement on Fatal Crash That Killed State Police Trooper Kevin Trainor

SALEM, Mass. – July 15, 2026 – Today, the Office of Essex County District Attorney Paul F. Tucker releases a summary and statement regarding the investigation into the fatal crash on Route 1 in Lynnfield that occurred on May 6, 2026. That crash resulted in the death of Massachusetts State Police Trooper Kevin Trainor, 30, of Georgetown, and Hernan Marrero, 50, of Roslindale.

The report cites the crash reconstructionist determination that Marrero’s wrong-way driving was not caused by any defect, malfunction or condition of his vehicle or any defect or condition of the posted signage, but rather “the collision was caused by the actions of Mr. Marrero and, furthermore, that his wrong-way operating of the Jeep ultimately resulted in his own death as well as the line of duty death of Trooper Kevin Trainor.” Toxicological testing showed Marrero’s blood alcohol concentration to be more than twice the legal limit.

The full summary statement from DA Tucker is available here.

“The available evidence is consistent with early reports that in responding to this highly dangerous situation, Trooper Kevin T. Trainor demonstrated exemplary courage and self-sacrifice,” Tucker said. “His willingness to put his own life at risk to serve and protect the citizens of the Commonwealth likely prevented an even greater tragedy.”

Tucker added, “Trooper Trainor’s ultimate sacrifice will continue to be felt deeply by the community and those he served with, including prosecutors and staff from my office. This tragic incident serves as a reminder of the profound risks our first responders face every day in order to preserve peace and maintain public safety.”
