As law enforcement closed in to arrest him, Minnesota healthcare fraud suspect Muhammad Omar chose to take a 50-50 risk of jumping off a fourth-story balcony in order to flee authorities on Thursday during a citywide joint FBI-Justice Department enforcement operation. At a press conference announcing 15 public healthcare fraud indictments in Minnesota, FBI Co-Deputy Director Christopher Raia asked the public for help identifying a fugitive who's a target in a Minnesota fraud investigation. "If you recognize this individual... If you can provide any information related to this individual, I would encourage you to call 1-800-CALL-FBI,” Raia said, showing video of a man limping away in flight after landing from his four-story jump. Whether he knew it or not at the time, Omar was taking a dangerous leap, since he had only a one-in-two chance of survival from a jump from four stories up, as Cambridge University’s Trauma Anesthesia 2nd Edition explains: “The median lethal distance for falls (LD50) is four stories or 48 feet (15 meters). This means that 50% of patients who fall four stories will die.” Despite hurting himself from the fall, Omar succeeded in avoiding capture by limiting away barefoot, likely aided by the benefit of adrenaline, which, as Biology Insights notes, helps people who are trying to “escape a dangerous situation”: “One significant effect is the temporary suppression of pain perception, allowing an injured individual to continue functioning and escape a dangerous situation despite discomfort. This analgesic effect enables focus on immediate action rather than the sensation of injury.”
