A northwest Missouri man has pleaded guilty to killing a co-worker with a hatchet and disemboweling a second woman seven months later.

Quintin P. O’Dell entered his pleas Thursday in Platte County Circuit Court on first-degree murder, two counts of armed criminal action, first-degree assault and deviate sexual assault charges.

He was then sentenced to two terms of life in prison plus 207 years, all running consecutively.

The 23-year-old Platte City man admitted killing 22-year-old Alissa Faye Shippert in May 2011 on the banks of the Platte River with a hatchet he picked up on shore as he walked upstream from his mother’s house.

He also admitted slashing the abdomen of a 21-year-old woman in December 2011 at her apartment in Ferrelview, southeast of Platte City.
