Just as she was preparing to leave her Macdonald campus office on May 24, 2022, Kelsey Tibbo, Operations Manager, Security Services, got a call from a patroller reporting that a man had collapsed in front of the Morgan Arboretum entrance and was unconscious.
Tibbo and another patroller hopped into the Security vehicle and drove to the Arboretum. Once there, Tibbo saw that the man – who had been cycling – was in cardiac arrest. Aided by an automated external defibrillator (AED), she performed CPR until she felt a pulse and saw that the man was breathing on his own again.
