Barbra Jean Tuttle, 45, was found dead in her Lansing, Michigan, home on May 13, 2004. The cause of death was ruled a brutal bludgeoning, and investigators treated the case as a homicide. The initial inquiry produced few leads and the investigation went cold for years.

A later pattern of violent crimes in the Lansing area focused attention on convicted felon Matthew Macon. Macon had a lengthy record of violent offenses including sexual assaults and home invasions; one of his later victims was found in the same house where Tuttle had been killed. That connection made Macon a prime suspect in Tuttle’s death, though the subsequent arrests, prosecutions and convictions centered on murders from 2007 and related crimes.

Does anyone have information about Tuttle, the house where she was found, or contacts who might help resolve what happened?
