D.C. police are investigating why they failed to alert a southeast Washington family that a man they reported missing was in the hospital.

Richard Morris was hospitalized for more than a month before relatives were notified in April. The 61-year-old died in July.

According to police records, detectives were assigned to investigate how Morris was injured after officers found him March 1 in an alley suffering from a severe head injury.

He was taken to George Washington University Hospital, where he was admitted in critical condition. One of Morris' daughters says she contacted the hospital and was told that no man matching Morris' description was admitted.

A hospital spokeswoman declined to comment, citing privacy laws.

Police Chief Cathy Lanier tells The Washington Post that the department is investigating the incident but declined to comment on the facts of the case because it remains pending.
