NEW YORK (AP) — A 18-year-old high school senior in New York City has been charged with federal arson after setting a fire that left a sleeping subway passenger severely burned. Hiram Carrero was arrested and did not enter a plea at his arraignment in Manhattan federal court. The incident, occurring around 3 a.m. on a northbound 3 train, is part of a troubling trend of violence on public transport in the U.S. U.S. District Judge Valerie E. Caproni denied Carrero’s release to home confinement, labeling the act as 'heinous.' Prosecutors described the victim's condition as critical, raising concerns about his survival. Carrero, who has no prior criminal history, faces a minimum of seven years in prison if convicted. His case has attracted attention not only due to its shocking nature but also regarding his background, as he lives with and cares for his disabled mother. As investigators looked at video surveillance to trace the suspect, they found Carrero matching the description of the perpetrator. This incident is reflective of a broader alarming trend seen across transit systems, raising questions about safety in public transit environments.
