Editor’s note: The story below should have described a gun and ammunition fired into the ground and air as .45-caliber, not 45 mm. The story below has been corrected.

A Longmont couple was arrested early Saturday morning after police received calls of a shooting at a bar downtown.

Miguel Nava, 28, and Candice Marrufo, 27, were both arrested on suspicion of felony menacing, reckless or negligent discharge of a firearm, tampering with physical evidence, obstructing a police officer, and disorderly conduct — discharges a firearm in public.

Nava also was arrested on suspicion of unlawfully carrying of a concealed weapon, reckless endangerment and possession of a firearm while intoxicated.

Marrufo also was arrested on suspicion of attempting to influence a public official, accessory to a known criminal, and violating both a protection order and bond conditions.

According to an arrest affidavit, Longmont police were called to Breaker’s Grill, 380 Main St., just before 2 a.m. on Saturday for reports of a shooting in progress.

No one was injured, according to police.

When they arrived, officers saw people running in all directions. They spotted Nava, who matched the description of the suspect, walking north on Fourth Avenue with Marrufo, his girlfriend.

Marrufo, who at first lied about her name, would later tell police she was at the bar with Nava when her friend started to get in a fight on the sidewalk outside, according to the affidavit. The couple left the bar to stop the fight.

An unknown man standing in the area then punched Marrufo’s friend in the face. Thinking that his girlfriend was the one punched, Nava then punched the unknown man.

Marrufo told police the suspect pulled out a “shiny wheel gun” at that point and fired two or three shots, the affidavit says. The couple began running away from the bar.

Marrufo said police had the wrong suspect, and that the real shooter had run east on Fourth Avenue. She said Nava carried the magazine for protection but doesn’t own gun, according to the affidavit.

When police contacted the couple, they refused to stop walking and said they weren’t involved in the incident at Breaker’s. Officer Samantha Calvetti drew her handgun and pointed it at Nava, prompting Marrufo to drop to the ground and comply with orders, according to the affidavit.

Nava refused to comply with Calvetti’s orders a number times before getting on his knees. When he did so, the officer saw a handgun magazine in his back pocket, according to the affidavit. The magazine held .45mm handgun rounds.

During the investigation, K-9 Rudi found a .45-caliber handgun wrapped in a sweatshirt on the sidewalk, just south of where police stopped Nava and Marrufo. Two .45-caliber shell casings also were found in front of Breaker’s and one was found lodged in the ceiling.

Police asked Marrufo if the sweatshirt was hers. She initially said no, but when they asked if they would see her wearing it in security footage from Breaker’s, she said, “Give me back my sweatshirt,” according to the affidavit.

After she was booked, police talked with Marrufo again. She said everything she first said was true, and explained she lied about her name because she was out of jail on bond conditions that forbid her to drink. She also said that, as she was walking away from the bar while holding her sweatshirt, an unknown man asked her for it.

Several witnesses told police they were afraid for their lives during the incident. Two witnesses later identified Nava as the shooter.

Both Marrufo and Nava will be formally charged in Boulder County Court on Sept. 12. Nava is being held on a $10,000 cash bond and Marrufo is being held on a $5,000 cash bond.

Nava has previous convictions for theft, possession of drug paraphernalia and various traffic offenses, according to Colorado court records.

Marrufo has previous convictions for second-degree forgery, driving under the influence and driving while ability impaired, according to Colorado court records.
