West Valley City Deputy Chief Mike Powell said police believe they have the "primary" suspects in the case, though he did not rule out the possibility of more arrests.
According to West Valley City police, Knight disappeared Nov. 23. His family reported him missing Dec. 8, and soon South Salt Lake and West Valley City police were investigating the case.
Officers eventually concluded that a group of people decided to kidnap Knight because he owed money for drugs. The planned kidnapping began in West Valley City, continued to South Salt Lake and finally ended up in Weber County. At some point, Knight was shot, an autopsy revealed.
Powell said the investigation into Knight's disappearance led police to his body Tuesday. Powell did not say how long the body had been lying in the snow, but he did point out that Knight had been missing since November. Knight's body was frozen when investigators discovered it, Powell added. He did not provide additional details about Knights gunshot wounds.
Powell also did not say more about the connection between the suspects and Knight, citing the ongoing nature of the investigation.
The four suspects were arrested and charged Wednesday. Leech and Seumanu were charged with murder and two counts of aggravated kidnapping, all first-degree felonies, as well as one count of obstruction of justice, a second-degree felony. Soules and Myore faces the same charges, minus the single count of obstruction of justice.
Court records show that all four suspects have criminal histories dating back to the 1990s.
Powell praised the collaborative efforts of police in West Valley, South Salt Lake and Weber County.
