Shortly after 11:00pm on Saturday night, officers with the Grand Junction Police Department responded to 2754 Unaweep Avenue on a report of an assault in progress. Upon arrival, officers located two adult male victims with stab wounds to their torsos, as well as another adult male, later identified as John Siviter, 62, who was shouting profanities and asking the male victims if they were dead yet. While he was being detained, an empty knife sheath was located on Siviter’s waist band, matching the brand and shape of one of two knives that were found on scene.
Siviter was transported to the hospital to be medically cleared. During an interview with GJPD personnel, Siviter stated he was trying to “kill everyone” because they were running their mouths.
When interviewed, both victims said that the three men were at the residence when an argument took place. Siviter retrieved a knife and attacked one of the males, and the other male jumped in to stop the attack. Both victims were stabbed in the process. Siviter then retrieved an additional knife, and also made threats to go get a gun. Both males victims were treated for non-life threatening injuries.
After receiving medical clearance, Siviter was remanded to the Mesa County Jail on two charges of Criminal Attempt to Commit First Degree Murder (F2) and one charge of Felony Menacing (F5).
