CHICAGO (CBS) — A Chicago area family has filed a wrongful death suit against UPS, two months after a truck hit and killed a 78-year-old woman in the Sauganash neighborhood.

“They’re grief-stricken and having a lot of trouble dealing with it,” said Brion Doherty, the attorney representing the family of Mayya Medovaya. “Miss Medovaya was extremely important to her daughter, her grandchildren and the community in which she lived.”

Doherty has filed a negligence lawsuit against UPS, after Medovaya was struck and killed by a parcel truck around 5 p.m. on Aug. 22, as she was crossing Peterson Avenue at Central Park Avenue.

“The UPS truck took a right into her,” he said.

Doherty said he’s trying to find out whether the lights were red or green. Regardless, he said Medovaya was in a crosswalk and the UPS truck failed to yield as required by state law.

“We’re making attempts right now to try to secure more evidence about the color of the lights, and the speed and angles and things like that of the UPS truck; and so I don’t want to speculate too much about it, but what we do know, regardless of the color of the light, Miss Medovaya was in a crosswalk there and the UPS truck failed to yield to her,” he said.

UPS said it does not comment on pending litigation, but expressed sadness for the family.
