Details Emerge in Murder, Dismemberment Case

Summit County believed Carlson knew about the murder of John Mayo, whose dismembered body was found along I-80 in Summit County. Until last night investigators did not have a lot to go on in the murder of John Mayo, but Carlson told police where it happened, how it happened and how they disposed of the body.

When agents caught up with Mark Allen Carlson, Summit County was eager to talk to the man who goes by the name "Neptune." Detectives say he gave them what they needed in the murder of John Mayo.

Chief Deputy Dave Booth: "They gleaned just a tremendous amount of information from him; he was very cooperative."

Mayo's dismembered body was found along a frontage road for I-80 not far from the Wyoming border. Carlson's story provided new information and confirmed detectives' theories.

Chief Deputy Dave Booth: "He saw what happened and saw what occurred, and to some extent participated, but he's claiming he's not the killer."

Carlson told investigators the killer and his friends used to hang out with Mayo at his house on Lake Street here in Salt Lake City. Carlson also told investigators that's where the murder happened in May 2004. But Carlson says he did not kill Mayo, even though he did help dispose of the body.

Carlson also told investigators why the man killed Mayo, who was a convicted child molester.

Chief Deputy Dave Booth, Summit County Sheriff's Office: "It was just a simple matter of he didn't didn't appreciate his criminal history, the things he had done, the lifestyle he was living, and decided to put an end to mister mayo."

Police say Carlson is a white supremacist gang member, but they do not think the accused killer has gang ties. Investigators will not name the accused killer but say he was a suspect early in the investigation. Carlson confirmed it.

Chief Deputy Dave Booth: "The information he gave us, matched up with what we found."

The accused killer is in prison on a federal parole violation and is not going anywhere. Summit County Detective will work with Salt Lake City detectives to put together the case.
