Three people have been taken into custody on charges stemming from July’s disruptive “Kill da Streetz” motorcycle ride in Denver, police announced Tuesday, with investigators calling the arrests the first of several to come.

Ryan Easton, of Pueblo, and Richard Patton and Clinton Hawkins, both of Colorado Springs, are suspected of exhibition of speed and reckless driving in the July 24 ride. The allegations are Class 1 misdemeanors and carry with them possibly jail time.

Doug Schepman, a Denver police spokesman, said authorities are in the process of transferring the trio to Denver.

The motorcycles belonging to Patton, 33, and Hawkins, 27, have been impounded. Authorities say they are in the process of finding a third motorcycle associated with the three that they hope to impound as well.

Police have been investigating the ride in order to identify those responsible and move for their prosecution. One possibility being explored, investigators say, is the seizure of motorcycles linked to the incident under the city’s public nuisance laws.

The ride strangled traffic in and around downtown Denver as hundreds of motorcyclists flooded the city’s streets and Interstate 25. Police say riders performed dangerous stunts, raced and generally acted recklessly. The incident prompted a large public outcry from those caught in strangled traffic or forced off the road by participants.

At one point during the July event, police say the mass of riders stopped and blocked all lanes of traffic on northbound I-25 near University Boulevard. The group was also seen disregarding red lights downtown and weaving in and out of cars on a crowded Park Avenue as fans headed to a Rockies game.

“This group claimed to be bringing attention to fatal motorcycle crashes, but their message was lost by the general actions of the group (and) specifically by certain riders,” Lt. Rob Rock, who supervises the Denver Police Department’s traffic investigation’s unit, told reporters Tuesday. “They created a substantial risk not only to themselves, but to other motorists in the city.”

Social media postings say the motorcyclists were part of a ride called “Kill da Streetz.” Police called the participants a loosely organized group who used Facebook to plan their ride. Rock likened the event to a flash mob.

Recordings of the ride have shown participants popping wheelies and “burning out” on roadways. Investigators say they used videos and social media postings as part of their investigation.

Rock said investigators are still gathering information on the ride and asked for the public’s help in providing additional tips.

“There were in excess of 100 people involved in this, not only riders but also support vehicles — vehicles that were driving around video taping this,” he said.
