Ronald Williams has been sentenced to 18 1/2 to 55 years in prison for the murder of Bobbie Maples.

Maples disappeared in December 2014 -- 11 days after giving birth -- and was found buried and wrapped in plastic. Williams pleaded no contest to a second-degree murder charge in August.

"No mother should have to bury their child," the mother of Maples told Williams in court Monday, Oct. 3.

Muriel Maples said Williams decided to "play God' when he killed the young mother just days after she gave birth to a daughter in Dec. 2014.

“She never made it back to comfort the new 10-day old baby girl and she never made it back to her seven-year-old son,’’ Muriel Maples said. “Bobbie will not be there to open her gifts her son got her for Christmas with the hopes that his mommy would still be coming home.’’

Maples’ body was found in January, buried under concrete in northern Muskegon County. Her mouth and nose were covered with duct tape and her head sealed in a plastic bag.

“Bobbie is now at peace,'' the mother said. "But I ask please do not let her die in vain. Do not let her death be worth anything less than life itself.’’

A plea agreement set his minimum term at 18.5 years. Muskegon County Circuit Court Judge Timothy Hicks set the maximum term at 55 years.

“No one should ever have to experience a death as Miss Maples did here,' Hicks said. "And no one should ever have her remains so horribly discredited as they were here.’’

Williams admitted to being the only person with Maples at the time of her death, and he claimed to have administered drugs to Maples around the time of her death.

When Williams has his first parole hearing in about two decades, the Maples family indicated they will be on hand to ask that he remain behind bars.
