Hildreth had been with the organization for 31 years.
"Words cannot express how shocked and devastated all of us are right now," Astros President of Business Operations Reid Ryan said in a news release. "Jamie gave so much of himself to the Astros organization and was loved and respected by so many in the Astros family and beyond. He had the unique ability to light up a room, no matter where he was. He was one of those people that no matter where he may be, someone would recognize him and come over to say hello. He truly was a special, one-of-a-kind individual and will be greatly missed. This is a very difficult time for us. We are in mourning over the loss of a very, very special man."
