gavelA 4.5-year prison sentence was imposed June 10 for a Kingman woman who dismembered her boyfriend before she collected his social security benefits for more than five years. Mary Killen, 57, pled guilty to theft of more than $56,000 in the case involving the 2010 death of William Felder, 71.

An investigative report indicated that Felder had suicidal ideations and that Killen told a detective that she found him dead in his home in Mohave Valley with pills in his mouth. Killen said she used a filet knife to dismember Felder where she found him on his bed, according to the report.

Killen told a detective that she put the body parts in plastic totes and put cat litter over them because she thought it would delay decomposition and minimize odor. Killen sold some of Felder’s belongings and took his dog “Snoopy” to the pound where it was destroyed.

Prosecutor Jace Zack said Killen’s actions were “ghastly” but that she was promised she would not be charged with abandonment of a body or tampering with evidence charges in exchange for her cooperation in telling authorities where they could recover the body parts where buried on her Kingman property. The body parts were located in plastic bags at two burial sites excavated in March.

Zack said the coroner has indicated she will be ruling Felder’s death as a drug overdose. He said Killen can still be charged with murder if it can ever be proved that she was involved in his death.
