According to the complaint, obtained by 9News, Kusick came to the attention of federal authorities on October 30 via his therapist, Corey Candeleria. The previous day, Kusick, in the company of his aunt and uncle, arrived for an emergency session following a confrontation between Mitchell and his parents, with whom he's been living.

The fight is said to have started over Kusick's withdrawal of money -- plenty of it -- from his savings account. In the midst of the argument, he allegedly "informed them that he was okay with homicide," at which point his dad ordered him out of the house. In addition, Kusick is said to have physically struggled with his mother and pushed her to the floor before heading to his aunt and uncle's house. There, he took one of their rifles and hid it in their home before heading to Walmart to purchase ammunition.

Fortunately, personnel at the store refused to sell Kusick what he wanted. He returned to his aunt and uncle's place sans ammo and went to sleep. Then, the next morning, his aunt found out he had the rifle and forced him to return it before hightailing it to the therapist's office.

What were his plans for the weapon? In conversation with Candelaria, he said he planned to use it "to kill children at a local high school on Halloween." His idea was to continue shooting until he could draw police into a firefight. He admitted to having had such homicidal fantasies over the course of five or six years, fueled by obsessions with events like the Columbine shootings, the slayings at Virginia Tech, and the abduction and murder of ten-year-old Westminster girl Jessica Ridgeway.

In addition, Kusick told his therapist that he'd been tracking President Obama's many visits to the Denver area during the just-concluded campaign season, because of his desire to go down in history as the "guy who killed Obama." Along the way, he noted that he'd practiced shooting an assault rifle on a firing range in Grand Junction, where he had attended what is now known as Colorado Mesa University; his Facebook page lists him as a nursing student at CMU, with an anticipated graduation date of 2015.

He also said he'd previously owned a couple of rifles, but his parents made him get rid of them -- and he also had a fascination with bombs. Thoughts of using them weren't new: He claimed that when he was a student at Broomfield High School, he'd obtained blueprints for the building and started plotting out a preliminary attack, with a special interest in trying to figure out the most efficient "kill zone."

These comments were more than enough for Candeleria to advise Kusick's aunt and uncle to have their nephew hospitalized. He was put on a 72-hour hold at Lutheran Hospital, after which the therapist contacted law enforcement.

On the 30th, Kusick confirmed all that he'd told Candeleria during an extended conversation with a Westminster police officer, and added plenty more.
