Suspects arrested after pursuit on Interstate 25

Two armed, wanted suspects were arrested after eluding law enforcement in an early morning incident.

On November 11, 2026, just after 11:45 p.m., Larimer County Sheriff’s Office received an automatic license plate reader alert of a vehicle with a stolen license plate at Highway 34 and North Denver Avenue in Loveland. Deputies found the vehicle and attempted a traffic stop, but the driver refused to pull over. As they pursued, deputies saw the driver waving a gun in a threatening manner.
 

Using tire spikes and law enforcement vehicles, deputies safely stopped the car at Interstate 25 and Highway 66. The driver, Sully Lewis (DOB 11/19/1994), was arrested and booked into the Larimer County Jail on the following charges, as well as an active El Paso County warrant:

• 1st Degree Assault (class 3 felony)
•  Vehicular Eluding (class 5 felony)
• Aggravated Cruelty to Animals (class 6 felony)
•  Prohibited Use of Weapons (class 1 misdemeanor)
•  Obstructing a Peace Officer (class 2 misdemeanor)
• Theft / Removal of a Vehicle License Plate (class 2 misdemeanor)
• Resisting Arrest (class 2 misdemeanor)
•  Possession of Drug Paraphernalia (drug petty offense)
• Vehicle Had No/Defective License Plate Lamps (traffic offense)

Additional charges are pending. In addition to the combined $108,000 cash/property/surety bonds from El Paso County, Lewis was issued a $35,000 cash bond by the Larimer County Court.
The passenger, Carissa Allen (DOB 02/22/1990), was taken into custody on active El Paso County warrants, which include a $50,000 cash/property/surety bond. Booking photos are attached.
 

Deputies recovered multiple firearms from the vehicle. They also rescued a pregnant dog that was inside during the pursuit.

"I’m thankful that our deputies are safe, resolved this situation, and prevented harm to other motorists," said Lieutenant Josh Fast. "Driving recklessly is completely unacceptable and puts innocent lives at risk. We will not tolerate this kind of dangerous behavior in Larimer County."

LCSO would like to thank Colorado State Patrol and Loveland Police Department for their assistance during this incident.These charges are merely an accusation, the defendant is presumed innocent until, and unless, proven guilty.
