Walter E. Lyman Jr., 76 and a former police chief in Raymond, New Hampshire, was found beaten and stabbed to death in his Old Manchester Road home on May 15, 1974. The scene indicated a violent struggle. Investigators pursued leads and examined evidence promptly after the discovery, but the initial investigation did not produce a resolution and the case grew cold.

Decades later the homicide remains unsolved. No arrests have been announced and the identity of any suspect or suspects and a motive are still unknown. The New Hampshire Department of Justice lists the case as unsolved.

If anyone knew Walter, his movements around Raymond in May 1974, or has information that could help, please share what is known.
