Overview
- The Essex County district attorney released the final investigative summary on July 15 that found Hernan Ramon Marrero drove the wrong way on Route 1 and collided head‑on with Trooper Kevin Trainor, killing both men.
- Toxicology reported a blood alcohol concentration of 0.192 and the presence of bupropion, and investigators documented that Marrero had been served multiple alcoholic drinks earlier that night at two restaurants.
- MassDOT camera footage and cruiser event data show Marrero entered the Peabody jughandle, grazed a guardrail, ran a red light, made an improper turn and traveled about 1.8 miles south in the northbound lanes before the crash.
- A State Police reconstruction concluded Marrero’s actions caused the collision, not a vehicle malfunction or faulty signage, and recorded impact speeds of roughly 56–61 mph for the Jeep and 60–68 mph for the cruiser.
- The Massachusetts Alcoholic Beverages Control Commission has issued civil notices to Tribu Mexican Kitchen and Bar with a July 28 hearing while state officials move forward on a multi‑year expansion of wrong‑way detection and prevention at more than 500 high‑risk locations.
