Federal agents and local police were investigating a Colorado Springs residence Thursday morning connected to the explosion of a Cybertruck in Las Vegas on New Year’s Day, authorities said. The man killed in Wednesday’s Cybertruck explosion was an active-duty U.S. Army soldier, federal officials told the Associated Press. Early Wednesday morning, a Tesla electric Cybertruck rented in Colorado and filled with firework mortars and camp fuel canisters exploded outside President-elect Donald Trump’s Las Vegas hotel.
