A summertime crime spree was a thrill for one of the young suspects, a detective said during a preliminary hearing.

Douglas County Detective Kal Collins said Brandin Kreuzer, 19, told him he did the crimes for “fun and adrenaline.”

Kreuzer and Taylor Moudy, 19, are suspects in a host of Douglas County crimes committed throughout the summer.

The charges include auto theft, firearms theft, theft of personal property and shooting a police officer.

Collins was one of the detectives questioned at Kruezer’s preliminary hearing Dec. 18 at the Robert A. Christensen Justice Center.

Kreuzer and Moudy were taken into custody Nov. 18 after a five-month investigation into what Castle Rock Police Chief Tony Lane called “the biggest crime spree in Douglas County we’ve seen in a long time.”

After almost six hours of testimony and questioning, Douglas County Judge Susanna Messner-Cutler concluded enough evidence existed against the suspect to bound the case over for trial. Kruezer’s next court date is Jan. 26, 2009.

Moudy’s preliminary hearing is set for the same day.

Collins said Kreuzer told him the adrenaline he felt from motocross riding didn’t even come close to the illegal exploits — they were a “greater thrill.”

One incident included stealing Hummers from a dealership in Castle Rock.

Collins said he was told by Kreuzer that he drove a stolen Hummer through the dealership window.

“It was pretty cool,” Kreuzer reportedly told Collins.

Collins said Kreuzer and Moudy used a code when they talked to each other, planning their next move. Kreuzer told him they would say, “Hey, are you going to (for example, Kelly’s) birthday party at 0200?” The Kelly referred to the location, and the time referred to when they would meet.

Stolen guns were used during the crime spree, authorities said, and Collins said the firearms were hidden at Kruezer’s parents’ residence. Detectives said they found one firearm under the couch in the basement where Kruezer was living and another in Kruezer’s father’s gun safe.
