Darryl Roman Burt II, 29, worked as a financial aid officer for Keiser University's Jacksonville, Florida, campus.
As a volunteer, he co-chaired a clothing drive for the homeless for the Jacksonville Jaycees, a nonprofit organization.
"Darryl was very passionate about working in the community and wasn't afraid to take the lead," Jacksonville Jaycees President Shawn DeVries told the Indianapolis Star. "If someone needed anything, he'd usually just ask for the details: where, when and what are the deadlines."
Burt left behind family in central Indiana, and recently earned a degree in human resources management.
Keiser University's chancellor, Arthur Keiser, called Burt "a highly respected member of the KU team" on the school's website, and the school was providing grief counselors to help Burt's colleagues.
