A short time later, a second runner collapsed from heart problem moments after crossing the finish line. Chief Inspector Joseph Sullivan, who leads the Homeland Security Unit, described how after the runner dropped to the ground in front of him and two medics, they instantly went into action, getting the runner breathing again.

Chief Inspector Sullivan told CBS 3’s Walt Hunter that Officer Fleming and Agent Hoffman are both EMT’s, part of a police FBI team that is assigned to the Broad Street Run and other major events like the July 4th Celebration.

Sullivan says he’s optimistic, based on initial medical reports, both runners are now on their way to full recoveries, adding he hopes, if they are inclined, “they’ll be back in the race next year.”
