DENVER -- Traffic records show that the suspected hit-and-run driver accused of slamming into a taxi -- killing the two women inside -- has a lengthy history of traffic violations.

Sandra Lee Jacobson, 40, was arrested after the crash on suspicion of vehicular homicide, vehicular assault and driving under the influence.

An arrest affidavit states Jacobson had "a strong odor of alcohol," and "was staggering" when officers confronted her. She "admitted to consuming Night Quil (sic) before and after the accident," according to the police report.

The two women killed en route to the Denver airport were identified as 54-year-old Kathy Krasniewicz and 71-year-old Kate McClelland, both librarians from Riverside, Conn.

Perrot Memorial Library Director Kevin McCarthy told the Greenwich Time that Krasniewicz was head of youth services. McClelland had retired from the library but still served as a children's storyteller, he said. The women had attended American Library Association conference in Denver.

Krasniewicz and McClelland were thrown from the purple Freedom Taxi minivan after it was hit by a pickup truck Wednesday afternoon. The taxi driver suffered non-life-threatening injuries.

The pickup driver took off but police officers tracked the vehicle to a cargo lot at Denver International Airport. Police said Jacobson was driving and had a passenger in the truck with her and several dogs in the back.

The taxi is not the first car Jacobson is accused of hitting.

Neil Holden said when he heard about the accident, he was sick to his stomach.

"I was blessed that she didn't kill me," he said over the phone from his home in Florida.

He recognized Jacobson from an accident two years ago that sent him to the Intensive Care Unit. Jacobson was convicted of running a red light in Jefferson County and causing that crash.

"She wasn't even supposed to be driving then. She was on a restricted license because of a 2006 DUI," said Holden. "We tried to get her jail time, but she reached a plea agreement ... Now, two people are dead because she was still driving."
