A Windsor woman suspected of drunken driving was arrested this weekend after she plowed into a patrol vehicle that had pulled over another suspected DUI driver on Old Redwood Highway, a sergeant said Monday.

Two deputies were investigating a suspected DUI driver when the woman, later identified as Nancy Camez Osuna, 32, came along and hit the back of the patrol SUV about 6:50 p.m. Saturday near Hembree Lane, Windsor Sgt. Jason Fowler said.

CHP officers responded to the crash and arrested Osuna on suspicion of misdemeanor DUI. She was booked into Sonoma County Jail and later released on $10,000 bail.

The first driver, 67‑year‑old Windsor man, also was arrested on suspicion of DUI, Fowler said.

Such crashes aren’t uncommon, and at times can be fatal. Last Christmas Eve, a 33‑year‑old Bay Area CHP officer died after a suspected DUI driver hit his patrol car as he and a partner were stopped along a Highway 880 offramp near Hayward.

“It does happen, more often than we like,” Fowler said of the potentially dangerous crashes.

No one was injured in the Windsor crash, although sheriff’s officials labeled it a close call. The crash caused rear-end damage to the SUV, which was being fixed Monday.
