Are dry ice bombs a thing now? Four dry ice bombs—two of which exploded—were found at LAX since Sunday, as investigators scrambled to figure out how they could have gotten in the airport in the first place. Dry ice bombs are literally a bottle with dry ice inside, but it’s deadly serious—and the suspects arrested could even be tried in federal court. A dry ice bomb exploded in the men’s room in a section accessible only to employees at the Tom Bradley International Terminal, police said. Two similar devices were found in the area. The three devices were found just one day after another dry ice bomb exploded in a men’s room Sunday night.
