VIDEO: Tucson's Fire Chief is retiring after 29 years in the department and six years as its chief. Chief Jim Critchley talked with us in the small museum at Tucson Fire Headquarters. He says he wants firefighters to always remember the 136 years of tradition and service the museum represents. He's especially proud of his time as training chief when he trained more than half the firefighters on the job now. "My legacy is those 300-400 people that came on in training and learned that we can do all this stuff but it's about the why; it's about the community that we take care of and that's what I'll miss"
