Veterans on Patrol, a group that helps homeless veterans, is asking for help from the public in finding a man that hasn't been seen since Friday.
Leaders with the organization say 66-year-old Brion Kawalek left the camp near Santa Rita Park on Saturday to go to Banner UMC.
He was discharged from the hospital, but never returned to the park.
Those that know Kawalek say he's only been in Tucson for two weeks and came from Mesa.
KGUN 9 has been told that Kawalek recently broke his hand and may have been at the hospital there for a check up.
A missing person's report has been filed with Tucson police.
