The man accused in a hit-and-run in Colonie that killed a Mohawk Valley man pleaded not guilty to elevated charges at an arraignment in Albany County Court Wednesday afternoon.

A grand jury indicted 33-year-old Brian Tromans on charges of criminal negligent homicide and tampering with physical evidence. Tromans had already appeared in city court on a charge of leaving the scene of a fatal motor vehicle accident without reporting it.

Tromans is accused of killing Master Sgt. Rudolph Seabron, of Rome, on Watervliet-Shaker Road in January. Tromans turned himself into police during the investigation; however, the DA's office says he hid his car trying to hinder the investigation.

"He was driving home; didn't think anything had happened," said defense attorney Lee Kindlon. "He thought he hit something in the road. He didn't think it was a person at all."

"The tragedy is no one even made an attempt to assist [Seabron]," said Albany County Legislator Merton Simpson, Seabron's cousin. "I understand shock and fear response, but you have to take responsibility for what we do to our fellow man."
