LIVINGSTON, N.Y. (AP) The Columbia County Sheriff's Office is investigating an accident in which the driver of a van has died.

Deputy sheriffs at the scene determined that the driver of a van going northbound on Route 9G shortly before 9:30 a.m. Thursday strayed into the southbound lane and struck a pick-up truck. The van operator, who was in critical condition, later died of his injuries at Albany Medical Center.

Two people in the truck also were taken to the hospital. Their injuries do not appear to be life-threatening.

Authorities are withholding the names of the accident victims until family members have been notified.
