EAST GREENBUSH — The taxi passenger who exchanged fire with state police and was wounded on a highway outside Albany has been identified as a 22-year-old from Connecticut.

According to State Police, Darryl O. Brown, of Hartford, remained in critical condition Sunday at Albany Medical Center.

Brown was the sole passenger in a taxi he hired to take him from Hartford to an undisclosed location in the greater Albany area, troopers said.

The cab was stopped on Interstate 90 in suburban East Greenbush shortly before noon Saturday for speeding, and Brown opened fire with an assault rifle on the trooper who was interviewing the driver and him.

Authorities said the trooper got the driver to safety. More police came, and Brown was shot multiple times.

The taxi, two trooper vehicles and two bystanders’ vehicles were struck by bullets, but no officers or bystanders were hit, police said.

The highway was closed for almost eight hours as police investigated and tagged evidence.

A couple from the Albany suburb of Delmar, returning from the Berkshires, told the Albany Times Union they were stopped in traffic when they saw a trooper running past cars and an SUV closing off lanes.

“It was pretty frightening,” said Devin McKeon, traveling with his wife Sacha, both 24. They heard “a volley of shots” and saw people running.

Another driver said what started with a traffic delay turned into terrified motorists and passengers fleeing from the gunfire.

Some backed up, others crossed the snowy median to go in the other direction, and others left their vehicles and ran, he said.
