Detective Rick Wall said two of McGregor's associates couldn't get in touch with him and that someone entered his room at the Grand America Hotel in Salt Lake City and found the 48-year-old unconscious. Police were called about 9 a.m. MDT and emergency workers arrived on the scene and were unable to revive him.
"There are no signs of foul play . . . Based on the initial investigation, [police and fire officials] did not see anything suspicious," Wall said.
The Rockies said McGregor was on a business trip with team chairman and CEO Charlie Monfort and executive vice president Greg Feasel. "Words cannot describe the level of shock and disbelief that we all are feeling this morning at the loss of Keli," Monfort said in a statement.
McGregor is survived by his wife, Lori, three daughters and a son.
McGregor was in his 17th season with the Rockies, his ninth as club president. He began his career with the Rockies in October 1993 as senior director of operations. He was promoted to senior vice president in 1996 and executive vice president in 1998.
His voice cracking, manager Jim Tracy said before the Rockies' game at Washington that he struggled with what to tell his team.
"I'm stunned. I can't believe what's happened," Tracy said. "I told the players in the clubhouse: 'I want to understand this, but I don't.' . . . We said a little prayer for him. The prayers are as much for him as for Lori and for those four children." - AP
