(CNN) -- Gabe Zimmerman used his degree in social work to help children in need. The avid runner and his fiancee had a lot of plans.
On January 8, those plans came to an end when he and five others died when a gunman opened fire at Representative Gabrielle Gifford's "Congress on Your Corner" event in Tucson, Arizona.
Friday, the congresswoman and her staff paid tribute to Zimmerman, Giffords' director of community outreach, on what would have been his 31st birthday.
A video featuring a montage of photos was posted on Giffords' Facebook page. The video featured a recording of "Roger and Out" by singer Neil Young.
"We are thinking of our friend and colleague, Gabe Zimmerman, who would have turned 31 today," the posting said. "Though cut far too short, we honor a life well-lived. Our thoughts are with his family."
Zimmerman, a Tucson native, joined Giffords' staff in 2006.
The congresswoman, who was one of 13 injured in the attack, is recovering at a Texas facility.
Meanwhile, shooting suspect Jared Lee Loughner, 22, has been moved from Phoenix to a federal facility in Tucson for a March 9 court appearance, according to U.S. marshals.
