A southwest Florida man has been sentenced to 50 years in prison for decapitating his girlfriend and sticking her head on a pole.
As part of a deal with Collier County prosecutors, 38-year-old Christopher Serna pleaded guilty to murder Friday.
A spokeswoman for the state attorney's office says the deal will save 45-year-old Suzanne Bishop's family from having to relive the case.
In July 2011, deputies found Serna covered in blood in his North Naples apartment. Next to him, deputies saw Bishop's severed head with a metal rod shoved through the bottom. Her body was found in a bedroom.
