"There's not a better person to be around. You could take every adjective there ever was that was positive and you could apply that to Raymond Scholwinski," said Harris County Sheriff's Office captain Michael Koteres.
Dozens of deputies gathered the day after Scholwinski passed, all touched by the presence of a great man.

"He was the best man that I ever knew. He was kind. He always had time for everybody," said Sgt. Joe Halm.
A man that touched so many lives.
"He was the most humblest sergeant, the nicest sergeant, the sergeant who was patient and willing to help anybody that needed help," said Deputy Emilia Wheeler.
Some called him Uncle Ray. He wasn't just a fellow officer, he was family.
Scholwinski has been married to his wife, Rynda for almost 34 years, they have four children, two together. When we talked to his wife in April, she talked about the kind of generous man he was.
"He touches people's heart when they meet him. He has a way of never meeting a stranger," Rynda said.
