The body of Senior Police Officer Ernest Leal Jr., 60, who had been fighting a weekslong battle, was given a police escort from the hospital to the funeral home.
"We have truly lost a man who defines what it means to be a public servant," Police Chief Art Acevedo said in a statement.
Leal began working in the county jail in 1984; in 1989 he transferred to the department's North Patrol Division, where he spent the rest of his life serving the city.
Doug Griffith, vice president of the Houston Police Officers' Union, said Leal was beloved and residents on his patrol went to the hospital where he was sick and held signs reading, "We Love You Officer Leal."
"Everyone out there said just how much he was a go-getter," Griffith told ABC's Houston station KTRK-TV. "He would always be on the scene, you know. He is always out there to help out and lend a helping hand and serve the community. It's an honor to have known him and his lovely wife, and we just want to keep them in our prayers right now."
