GUILDERLAND — Monday morning, a van crashed into the brick wall of the SEFCU building on Route 20. It forced the wall into an office, knocking a desk askew.

The assistant manager who sits at the desk doesn’t work on Mondays, according to the branch manager, Matthew Speciale, so no one was hurt.

The State Employee Federal Credit Unit calls its customers members. “Thankfully, neither the member nor any staff was hurt at the Guilderland branch,” said Michael J. Castellana, SEFCU president and chief executive officer, in a statement emailed in answer to Enterprise questions.

“While there is some damage to the building, it isn’t structural, and the branch will remain open for normal business hours,” Castellana said on Monday.

Curtis Cox, deputy chief of the Guilderland Police, said the van, a 2009 Honda, was driven by Jane O’Connor, 84, of Brookview Drive in Guilderland.

“The driver of the vehicle does not remember what happened,” said Cox. “It may have been a medical issue.”

Police recorded the time of the accident as 10:28 a.m.

Asked about the cause of the accident, Cox said, “She remembers hearing a lot of noise and then went into the building.”

No charges are being pressed, Cox said, a decision made “at the officer’s discretion.” Dan Colbert was the arresting officer.

The driver was not transported to any medical facility, said Cox.

Asked if O’Connor would continue to drive, Cox said, the state’s Department of Motor Vehicles has a driver review program. “Anybody can be referred; it can be by the police or by the family,” said Cox.

He did not know if Colbert had referred O’Connor to the program.

O’Connor could not be reached for comment.
