A special prosecutor says several factors support imposing the death penalty against a Cheyenne man accused of gunning down two people and critically wounding a third last summer.

Nathaniel Castellanos has pleaded not guilty to first-degree murder charges in the August shootings of 21-year-old Corey A. Walker and 25-year-old Megan L. McIntosh, both of Cheyenne. Castellanos pleaded not guilty to attempted murder in the shooting of another woman.

Casper District Attorney Mike Blonigen listed factors made public this week that he says would support imposing the death penalty against Castellanos.

Blonigen alleges Castellanos’ actions created the risk of death to two or more people, that he’s likely to commit more violence, that McIntosh’s murder was especially cruel and that Castellanos committed murder to avoid arrest.
