Officers and detectives responded to Walter Street in Chicopee around 10:30 a.m. on Sunday and found evidence indicating a possible crash at the edge of the river, the Massachusetts State Police Dive Team responded and found the submerged car, which was removed from the river around 7 p.m. Sunday, according to the Hampden County Sheriff’s Office.

They said it is not yet known whether Callahan was driving the vehicle when it went into the river.

The Hampden County Sheriff’s Office said its Marine Patrol Unit is assisting the Chicopee Police Department, the Chicopee Fire Department and the Western Massachusetts Regional Dive Team in the search.
