Family members and friends describe Miller as a family man, a brother, husband, and father, who dedicated his life to helping others.
"We have always been so proud of Gary for what he did," said Gayle Murrell, his sister. "Serving people, that was his heart."
Miller, a 33 year Columbus law enforcement veteran passed away Wednesday after a year-long battle with Glioblastoma, a form of brain cancer.
"He would do anything to keep himself alive and would do it for his family," she explained. "But, he really struggled through this cancer. He's at peace and is with God. He's been saved. He's at home. He doesn't have to suffer anymore."
His sister, Gayle Murrell remembers her brother as a good man and a workaholic that everyone knew.
"The thing is, everywhere I go, I've talked to somebody or meet somebody and almost everybody knows of this man," she recalled.
Bill Thrower, Muscogee County's Corner, said his good friend, who also served in the military, was the hardest worker he ever knew.
"It was great. Because, when he'd come on the scene of crimes, when we were working together, he knew exactly what had to be done," Thrower explains. "And, he did it no matter what the conditions were. He was a man. He was a strong willed man, a hard worker. As far as I'm concerned, he never gave up on anything that he tried to do."
He leaves behind family and friends, a daughter, son, and wife.
