Man flees Summit County police officers in 100-mph motorcycle chase

A routine traffic stop turned into a 100-mile-per-hour motorcycle chase last week after the rider eluded two law enforcement officers, ran several red lights and narrowly avoided a pile-up while driving in the wrong lane before being taken down by a sheriff’s office canine, police say.

Brandon David Mumma, age 35, was on bond at the time of the chase for a July 4 arrest in which he allegedly started a fight in front of a bar in Breckenridge and then resisted police.

Before the July 13 chase, Mumma was allegedly seen riding a motorcycle at 71 mph in a 55 mph zone near U.S. Highway 6 and Lakeside Drive in Dillon.

When a Summit County Sheriff’s deputy attempted to pull him over, Mumma looked back over his shoulder and then sped away “to well over 90 mph,” according to an arrest affidavit.

At a red light on Highway 6 and Evergreen Road, Mumma allegedly slowed down “for a split second” and then accelerated through the red light “at approximately 100 mph.”

The sheriff’s deputy stopped his chase and called in Mumma’s description over the radio, noting in his report that there was heavy traffic at the intersection.

A Dillon police officer then attempted to stop Mumma near Lake Dillon Drive and LaBonte Street, but he allegedly sped away at 80 mph in a 25 mph zone.

A sheriff’s deputy later observed Mumma speed through another red light at Swan Mountain Road and Colorado Highway 9. The deputy pursued Mumma and cut him off from making a U-turn, so Mumma instead turned around and headed north in the southbound lane.

Mumma “narrowly avoided a four-car pileup,” the affidavit says, before pulling into a driveway north of Breckenridge. There, he got off his motorcycle and “started explaining to (the deputy) that he was not going back to jail.”

A scuffle ensued, and Mumma allegedly tried to elbow the deputy in the face. He then turned and started running away, so the deputy sent his canine “Danny” after him.

Danny subdued Mumma with a bite to the back of his shoulder, prompting him to put his hands behind his head and cooperate, the affidavit says.

 Mumma was charged with 11 criminal counts including speeding, vehicular eluding, reckless endangerment and resisting arrest. He was released on a $7,500 bond the next day, the court clerk’s office said.

According to an arrest affidavit for his July 4 arrest, Mumma confronted a man because he was wearing a military-style jacket despite not having served. Mumma grabbed the jacket and demanded the man take it off before allegedly hitting him across the face with an open palm.

Officers separated Mumma and attempted to restrain him, but he became very combative and started shouting profanity, the affidavit says. He then claimed he was going to “sue the (expletive) out of” the officers and said he “couldn’t wait to get rich off” them.

Several police officers were able to handcuff Mumma, who appeared to be intoxicated, and place him in a patrol car. After they closed the door, Mumma began trying to kick in the window and caused roughly $1,000 in damage, according to the affidavit.

After officers opened the door to prevent further damage, Mumma allegedly started spitting at them.

He was charged with third-degree assault, criminal mischief, disorderly conduct, harassment, resisting arrest and two counts of assault on a peace officer.
