A Boston man is facing charges after authorities say he boarded an MBTA Commuter Rail train with a homemade explosive device, turning an ordinary ride into a tense hazmat scene. Hazardous-device technicians later examined the suspicious container, during which fireworks inside reportedly detonated before the device was neutralized. No injuries were reported. The suspect, 29-year-old Shane Cautillo, was ordered to return to court later this month, and the case is already prompting fresh questions about security on regional rail lines.
What officers say they found
According to police, officers initially spotted a large, disconnected lithium battery, an electric towel warmer with wires protruding from it, and an electric scooter with a bag attached. An X-ray and subsequent search allegedly revealed that the towel warmer contained a duct-taped lithium battery, several small tool batteries, a water bottle, a cell phone, a power adapter, and a container of BOOM Margarita wine cocktail, as reported by WHDH.
Explosion during neutralization
A hazardous-device technician evaluated the package, and an X-ray reportedly showed what looked like a power source, fusing, an explosive charge, and a switch inside the container. While officers worked to render the device safe, several fireworks inside ignited and caused an explosion. Even so, “The technician was able to neutralize the device,” WHDH reported, and no one was hurt.
Arraignment and reported motive
Cautillo was arraigned last week, and prosecutors said he is scheduled to return to court later this month, according to WHDH. A witness told investigators the man claimed he was inspired by the January 6 attack on the U.S. Capitol, the station reported. Prosecutors have not yet released any further details about a possible motive.
Why those components are dangerous
Federal safety guidance from OSHA warns that lithium batteries, if damaged or shorted, can enter “thermal runaway,” a failure that can quickly lead to fire or explosion, especially in tight, improvised setups. And because consumer fireworks contain energetic, combustible materials that can ignite or explode when confined or wired into a circuit, packages that combine batteries and pyrotechnics are treated by bomb technicians as potentially life-threatening explosive devices, according to the ATF.
Cautillo is expected back in court later this month as prosecutors continue their investigation. Authorities say the probe remains active, and they anticipate releasing more information as additional charges are considered and the case moves forward.
