The City of Bryan and its police force said good-bye Friday to one of their own.
Bryan police officer Jim Do was laid to rest Friday afternoon.
Do passed out while running on Monday.
A preliminary autopsy report showed heart disease as the cause of death.
Hundreds of people turned out to celebrate his life.
"Most of the department members are in a state of shock and disbelief," Bryan Police Assistant Chief Peter Sheets said. "Officer Do was 34 and from all appearances he was in excellent health, so the department is coming to terms that he's passed away."
Police cars filled the parking lot at Central Baptist Church as support came in from around the state.
As his comrades stood at attention, and his family looked on, they remembered Do as the man he was.
"I think they should be proud of him," Sheets said. "He was a dedicated professional with a good sense of humor and he lived and breathed police work. He was doing what he wanted to do."
For that, he was honored for his service.
And as the shock of his unexpected death subsides, the memories of a man known for his humor and desire to serve, won't fade.
Officer Do was a graduate of Texas A&M University.
He joined the Bryan Police Department in August of 1999 and served as an officer and a member of the Tactical Response Team.
His wife is expecting the couple's first child.
