A former Colorado deputy was arrested after police said he fired an AR-15-style rifle at the Boulder County Sheriff’s Office and police vehicles at the Broomfield Police Department.
According to the Boulder County Sheriff’s Office, the suspect was identified as 40-year-old Tyler Boyd Reilly, who had previously worked for the sheriff’s office. He was taken into custody on Sept. 28 after being confronted by deputies outside the sheriff’s office.
It all began when a man called the sheriff’s office at 12:02 a.m., reporting experiencing anxiety before calling back several minutes later, making threats toward the Boulder County Sheriff’s Office facilities, according to authorities.
The threats quickly turned into gunfire. Police say Reilly traveled to the Boulder County Sheriff’s Office and the Broomfield Police Department, where he fired multiple rounds before being arrested at the sheriff’s office without further incident.
Former Deputy Returns
The sheriff’s office said Reilly had worked for the agency from 2012 until May 2024, when he resigned in lieu of termination for cause. He worked in both the jail and patrol divisions.
Law enforcement determined that the calls were being made by Reilly and began searching for him after receiving them. They were able to track his vehicle traveling north on State Highway 287.
Gunfire Ensues
At about 1:08 a.m., a Boulder County sheriff’s sergeant spotted Reilly at the front entrance of the headquarters.
Authorities say Reilly was armed with an AR-15-style rifle and fired rounds toward the building’s entry area. No one inside was injured, and Reilly did not get into the building.
Investigators say they determined Reilly was also the suspect who was at the Broomfield Police Department, where authorities say he fired multiple rounds at police vehicles.
Despite Reilly firing at the sheriff’s office and Broomfield police vehicles, no law enforcement officers fired their weapons during either incident. Sheriff Curtis Johnson said in a news conference deputies used communication, patience, and tactical positioning to get Reilly to surrender without anyone being seriously injured.
The Charges
Reilly was booked into the Boulder County Jail and faces multiple charges from the sheriff’s office, including attempted first-degree burglary, felony menacing with a deadly weapon, criminal mischief, attempted first-degree criminal trespass, prohibited use of weapons, resisting officers, reckless endangerment, and obstructing governmental operations.
He also faces charges from the Broomfield Police Department incident, including felony criminal mischief between $100,000 and $1 million in damage, second-degree criminal trespass, reckless endangerment, and obstructing governmental operations. After his arrest, Reilly was additionally charged with second-degree assault on a peace officer causing bodily injury.
Authorities said the charges may change as the investigation continues and did not give information regarding his bond.
No injuries have been reported in either incident. Reilly is presumed innocent unless proven guilty in court.
