DENVER -- A suspected hit-and-run driver accused of slamming into a taxi -- killing the two women inside -- was charged with two counts of vehicular homicide and other charges, authorities said Monday.

Sandra Jacobson also faces two counts of leaving the scene of an accident resulting in death and DUI, said Denver district attorney spokeswoman Lynn Kimbrough.

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.

Jacobson has been released from custody on a $50,000 bond. She is scheduled to appear in court on Feb. 13, Kimbrough said.
