ROCHESTER, N.Y. (AP) — A Rochester police officer has been killed in the line of duty for the first time since 1959, fatally shot during a pursuit.

Rochester Police Chief Michael Ciminelli said the officer was shot just before 9:30 p.m. Wednesday, during an exchange of gunfire with a suspect during a chase.

Ciminelli says the suspect was wounded in the exchange and was in surgery early Thursday. He said a bystander sustained non-life threatening injuries.

None of the three was identified.

The officer was taken to Rochester General Hospital, where he died. The others were taken to Strong Memorial Hospital.

Ciminelli said there are no other suspects and that an investigation was continuing.

He said more details would be released later Thursday.

UPDATE 12:55- The office killed in last night's shooting has been identified as Daryl Pierson.

Pierson was an eight-year veteran of the Rochester Police Department.

Meanwhile, Governor Andrew Cuomo has directed that flags on all state government buildings be flown at half-staff on Friday in honor of Officer Pierson.
