Rodolfo Ayala-Ayala, 33, was a biologics supervisor at the OneBlood donation center, according to the Orlando Sentinel.
"He's alive in the people's lives that he saved," said Mat Simons, who worked under Ayala-Ayala and said his supervisor was also a blood donor.
Ayala-Ayala had bought a car and a house within the past year. Wednesday would have been his one-year anniversary of home-ownership.
