A pair of female pedophiles and their two male friends plotted to kidnap, torture, rape and murder a child.
Matthew Toole, 33, became the last of the vile quartet to be sentenced for the scheme on Monday, and was jailed for between 25 and 50 years for first-degree criminal sexual conduct.
He was handed a further sentence of between seven years and 50 years over the kidnap plot.
Toole, of Battle Creek in Michigan, will also serve a separate 50 to 140 year sentence concurrently over child pornography offenses committed in a neighboring county.
Toole was arrested in August 2018 after embarking on the sickening plan with pals Jayme LaPointe, 20, Talia Furman, 33, and David Bailey, 37.
LaPointe and Furman struck separate plea deals last August and September which saw both women sentenced to between 25 and 50 years jail.
LaPointe previously pleaded guilty to first-degree sexual assault of a child after she and a man filmed themselves sexually assaulting a baby in October 2017.
She and her gang of pedophiles were busted after police were tipped off that they were members of a child pornography ring.
Furman and Toole were subsequently found to have child sex abuse images on their phone, WOOD reported.
Communications between those perverts and LaPointe as well as Bailey exposed their horrific kidnap and rape plot.
It was never brought to fruition, and no child came to further harm at the hands of the child abusers.
