GUILDERLAND — Town police are investigating an early-morning accident on Monday on Western Avenue that left pedestrian Sarmeen Siddiquee, 47, with what police say appeared to be serious injuries.

At the intersection of Western Avenue and Johnston Road, police say, a vehicle driven by David Romey, 54, of Berne, struck Siddiquee, who lives on Westmere Terrace in Guilderland, as she crossed from the north to the south side of Western.

Reached by phone on Monday afternoon, Romey said it was dark at the time, but declined further comment.

The accident occurred at 5:50 a.m. and caused the eastbound lanes of Western Avenue to close for about two hours as investigators worked to gather information. The accident was about 45 minutes before sunrise.

Siddiquee was transported to Albany Medical Center, police say.

The media relations office at Albany Medical Center Monday afternoon said that the center does not have a patient by that name.

Westmere Terrace is one block west of Rapp Road — which leads to Crossgates Mall Road — on the north side of Western Avenue. There is no crosswalk across Western at Westmere Terrace, although there is at the other side of Rapp Road.

According to her Facebook page, a Sarmeen Siddiquee from Dhaka, Bangladesh works as a cardiorespiratory technician at Albany Medical Center and lives in Guilderland.
