Richard Keech, 89, was serving a life term for shooting his son-in-law to death in Long Beach in 1996. He suffers from dementia. The judge says there's no obvious benefit to his further imprisonment. In a quiet residential neighborhood in Long Beach 13 years ago, Dick Keech fired four shots at his son-in-law, who lay face-down on a neighbor's lawn, bleeding from an earlier gunshot wound.
