Collier killer wrote about mutilating bodies

FORT MYERS, Fla.- Brand new, never-before-seen evidence has just been released to WINK News in one of the most graphic murders in Collier County history.

Christopher Serna, 38, stabbed his girlfriend more than a 100 times four years ago, decapitated her, then put her head on a spike.

Serna just reached a plea deal and will spend 50 years in jail.

Authorities interrogated Serna for nearly an hour and a half the night they found his girlfriend’s body inside his apartment.

“I don’t know what we are going to talk about,” said Serna during his interrogation.

Serna sat there with a twitch, confused, his hands were bandaged up and he was covered in blood.

Serna: “I don’t know what you want me to tell you.”
Investigator:  “I want you to tell me what happened to Suzanne.”
Serna: “Suzanne?”

In July of 2011 authorities found 45-year-old Suzanne Bishop’s dismembered body in Serna’s apartment. They say she was decapitated and her head was placed on a spike.

Investigators also say Serna scattered bishops body parts throughout the apartment. In the interrogation, Serna never told investigators about what he did to Bishop. Only saying she wouldn’t leave his apartment.

But Serna did talk about Christine Moretz, a co-worker, who was shot to death by her husband nearly three weeks before. Investigators say Moretz was having an affair with Serna.

Serna: “Her husband shot her because of me.”
Investigator: “Because of you?”

Another shocking discovery was Serna’s journal authorities found his fingerprints all over it. Inside he wrote of fear, hate, rape and mutilating bodies.

A picture shows people being hung from a tree. Serna also wrote things like “I kill– no regards for human life.”

Serna: “Tell them God says that we love them.”
Investigator: “Okay.”
Serna:  “That is what you can tell my family.”
