Four days after she became the victim of a hit-and-run on the corner of York and Elm streets, Andromahi “Mahi” Trivellas’ ’11 condition has been upgraded to “fair” and no longer life-threatening, a Yale-New Haven Hospital spokesperson said Wednesday night.

The Branford freshman was hit by a car — believed to be a white Oldsmobile or Crown Victoria with a blue top — at 1:05 a.m. Sunday, New Haven police said. She was rushed to the hospital for head and spinal injuries, where she remained in critical condition earlier this week.

The NHPD discovered a “vehicle of interest” Monday afternoon that fits the physical description given by eyewitnesses, NHPD captain Steven Verrelli said at a Monday press conference. The NHPD is in the process of obtaining and analyzing surveillance tapes of the intersection from businesses near the accident site, though the full investigation may take months to complete, Verrelli said.

An electronic sign displaying the speed of passing cars was installed soon after the accident on Elm Street between College and High streets — just over a block past the scene of Sunday’s hit-and-run — to enforce the 25 mph speed limit.

Verrelli requested that anyone with information about the Sunday hit-and-run contact the NHPD immediately.
