Swasey was a six-year veteran of the university's police force.
Four civilians and five police officers were taken to hospitals with gunshot wounds. The injured victims were in good condition Friday night, police Lt. Catherine Buckley said.
"The officers, they're obviously in some pain, but thankfully they're alive and talking to us, and they're heroes ... The courage they displayed today saved many, many lives -- no doubt," Colorado Springs Fire Chief Christopher Riley said.
In a statement released late Friday, Planned Parenthood CEO Cecile Richards thanked law enforcement officers.
"Our hearts go out to the families and loved ones of the brave law enforcement officers who put themselves in harm's way in Colorado Springs," she said.
The Planned Parenthood family grieves for Officer Garrett Swasey's family, friends and colleagues dealing with heartbreaking loss tonight.
