Contained on an Aurora Police Department arrest warrant
A photo of an arrest warrant for a former Aurora police sergeant shows damage caused by an exploding pipe bomb. The sergeant is charged with allegedly assisting the alleged bomber in covering up evidence.
A retired Aurora police sergeant is charged with allegedly helping cover up evidence after the man built pipe bombs and exploded two of them in residential areas in late 2020 and early 2021.
Curtiss Christensen, who resigned from the Aurora Police Department in 2006, was arrested on March 3rd, The Sentinel in Aurora first reported.
Christensen rented a room in his home to alleged bomber Scott Campbell, who was previously with his daughter. Christensen faces three criminals for allegedly knowingly buying a gun for a criminal, being a part of the bombings, and destroying evidence.
“The fact that Curtiss Christensen directed Scott Campbell to ‘get rid of everything’ before the (Bureau of Alcohol, Tobacco, Firearms and Explosives) got involved is significant,” one investigator wrote in the affidavit of Christensen’s arrest. “Curtiss Christensen is a retired police sergeant and would know from experience that the ATF is primarily responsible for investigating explosives and firearms allegations. This message would coincide with Curtiss Christensen, who advised Scott Campbell to destroy evidence of his involvement in the pipe bomb detonations. “
Campbell is suspected of setting off two homemade pipe bombs in residential areas in Aurora – one on Christmas Day and one on January 7th. No one was injured in the explosions, but investigators said on an affidavit that it was a matter of luck. Splinters up to 5 cm wide penetrated people’s windows and flew into houses.
The coalition of local and federal law enforcement officers tasked with investigating the explosions “understood that the likelihood of someone being injured or killed in the detonation of one of these explosive devices is very high,” according to an affidavit for Christensen’s arrest.
Investigators were able to connect Campbell to the bomb using traces of DNA found on the splinter. Police then monitored an address associated with Campbell and discovered that a car registered at that address belonged to Christensen. The car matched the description of the vehicle used in the two bombings.
Investigators issued a search warrant for the house on January 15 and, according to an affidavit, found bomb-making materials, a pistol, an AR-15 rifle and a partially constructed pipe bomb. Police that day arrested Campbell, who confessed to building the bombs used in the two explosions, and wrote a letter of apology to the victims, investigators wrote in the affidavit.
After Campbell’s arrest, police confiscated his phone and found messages between him and Christensen.
After the initial explosion, Campbell Christensen texted him – he called him “Sergeant” – asking for help hiding the car and trailer he’d been using when he allegedly detonated the pipe bomb, according to the affidavit. Christensen responded and helped him figure out what to do, including advice not to store the vehicle in a garage as it will leave a paper trail, his affidavit said. A few days later, he donated the car in what investigators believe was an attempt to hide evidence.
The texts also indicated that in October Christensen had bought a rifle for Campbell who, according to the affidavit, could not legally do it on his own because he was a felon. Christensen’s wife also told investigators that her husband bought the gun for Campbell.
Investigators arrested Christensen on March 3, according to court records. The affidavit for Christensen’s arrest was written by an Aurora police officer who works for the Regional Network’s Violent Crimes Task Force – a multi-agency team investigating violent crimes in the Denver area.
He was released from prison after putting $ 75,000 on bail. He is due to appear in court on March 30th. Christensen did not respond to a request for comment on Thursday.
