DENVER -

A shooting at a Denver retirement community Thursday left one person dead and another person in critical condition.

The Denver Post reports that the shooting at Metro Manor may have been done by a disgruntled resident.
    
Relatives of the alleged gunman told the newspaper that he lived at the complex and had issues with staff because he did not like them going into his room.
    
Relatives and eyewitnesses said that the resident argued with the manager, then returned with a shotgun and shot the manager.
    
Police have confirmed only that two people were shot in the incident, including the gunman.
