CASTLE ROCK, Colo. -- A Denver police officer said that he's the father of a 19-year-old arrested on suspicion of shooting and wounding a Douglas County deputy.

Kevin Kreuzer told the Rocky Mountain News in Thursday's editions that he's the father of Brandon Kreuzer.

Brandin Kreuzer and Taylor Moudy, 19, of Castle Rock were arrested Tuesday on suspicion of attempted first-degree homicide, burglary, robbery and motor vehicle theft.

Investigators said they believe one or both men shot at deputies on June 28 in Castle Rock. One deputy was treated for an arm wound and released.

The elder Kreuzer said he's distraught over his son's arrest and hasn't been able to talk to him since he was taken into custody.

"I don't know what to say," he said. "I can't believe this is happening. I don't know what has happened yet, and I'm waiting to hear the whole story."

Moudy is a student of the University of Colorado in Boulder and arrested on campus Tuesday.

Brandon Kreuzer's bail was set at $3 million and Moudy's at $2 million.

In a Wednesday morning news conference, Duffy said the suspects are linked to at least 17 auto thefts, one attempted auto theft, two vehicle trespasses, six home burglaries, one attempted home burglary, two police pursuits, an armed robbery and the shooting of the deputy.

The crime spree occurred between May 29 and June 28 in unincorporated Douglas County and Castle Rock.

Police said the suspects were caught on surveillance video during an armed robbery at the Circle K Convenience Store in Castle Rock on June 11. The video shows two men clad in all black military-style wear, brandishing a semiautomatic assault rifle.

The suspects also stole weapons, which they used to carry out their crime spree, Duffy said. The weapons have since been recovered.

Police don't know the motive behind the crime spree and why it abruptly ended after June 28. That is the day that dozens of deputies, SWAT team members and a police helicopter pursued the suspects. Police first received a call about a burglary in progress early that morning. Deputies spotted the vehicle and attempted to stop it but the suspects fled and fired into the patrol car, striking a deputy in the arm.

"Anytime you're dealing with individuals who would actually shoot at law enforcement officers, to society, those are the most dangerous individuals because if they're going to shoot at law enforcement officers, they will not hesitate to injure civilians," Duffy said.

A massive manhunt ensued after the pursuit but the suspects were never found.

The deputy was treated and released shortly after the shooting. He is back on the force and "doing quite well" but he's not allowed to speak about the case publicly because the investigation in ongoing, Duffy said.
