The police officer who was instrumental in getting life-saving defibrillators into Walpole police cruisers was saved recently by fellow officers using one of the devices to restart his heart at the police station. Patrolman Robert Simmons collapsed of an apparent heart attack during roll call at the station before the July 3 fireworks, according to Deputy Chief John Carmichael. Officers started CPR and one ran to get a defibrillator. “It took two shocks, but they got him breathing again,” Carmichael said. “He’s doing great, and is out of the hospital. It made for a good night knowing that we had a situation like that, and we ended up being OK in the end.” Carmichael said Simmons maintains the department’s defibrillators, and was a leader in getting the town to place one in every cruiser, as well as at the police station.
