Mae Mason was a 79-year-old resident of Alpine Manor nursing home in Walker, Michigan, who died in 1987 and was later ruled a homicide. Her death became part of a series of killings at the facility carried out by two nurse’s aides, Gwendolyn Graham and Catherine Wood. The women, who had a romantic relationship, are reported to have suffocated several elderly residents; suffocation initially allowed the deaths to be mistaken for natural causes.

The case came to light after Wood’s ex-husband alerted police in 1988. Wood told investigators that Graham was the primary instigator and that Wood sometimes acted as a lookout. Warrants were issued in December 1988; both women were arrested. Testimony in the proceedings included Wood’s accounts and a statement by Graham’s subsequent girlfriend that Graham had confessed.

Graham was convicted of five counts of murder and a conspiracy count and received five life sentences. Wood was convicted on lesser counts and received a term of 20 to 40 years. Did anyone at Alpine Manor notice changes in care or who worked particular shifts during the periods these residents died?
