Police in Tigard arrested a pair of suspects Wednesday after they say a dustup at a local bar spiraled into a wild shooting and car pursuit that a patrol officer witnessed firsthand.

The brouhaha began at Lu’s Sports Bar & Lounge after an argument erupted between two couples at the Southwest Pacific Highway watering hole, said Stefanie Kouremetis, a Tigard police spokeswoman.

One of the couples called it a night and split.

Instead of leaving the beef at the bar, the other couple, identified as Cristy Anna Sisco, 34, and Carlos Alberto Quebrado, 35, decided to hop into a gold Ford Escape and take off after their newfound foes, according to police.

The feud escalated when police say Sisco, riding in the passenger seat, whipped out a Dickinson 12-guage shotgun and opened fire on the first couple’s car, Kouremetis said.

One of the rounds struck a woman in the car, who suffered a non-critical injury, police said.

The wounded woman called police around 2:40 a.m. to report she and the man she was driving with were being shot at from a vehicle trailing them near Southwest Nimbus Avenue and Scholls Ferry Road, Kouremetis said.

During the call, a Tigard patrol officer happened to see Sisco holding the shotgun out of the Ford Escape, police said. The officer hit his lights and siren, prompting Quebrado and Sisco to jump out of their car and flee.

Police quickly arrested Sisco. Quebrado managed to spend more than two hours hiding out in Fanno Creek before he was taken into custody later, according Kouremetis.

Authorities booked the couple in the Washington County Jail, records show. Sisco faces an attempted murder charge. Quebrado was lodged on a felony warrant out of Marion County.
