Press Release  Man Charged With Murder In Columbus Avenue Shooting

Pittsfield — Tyler Sumner, 25, of Adams was arraigned in Central Berkshire District Court on a single count of murder on Monday.

He is being held at the Berkshire County House of Correction without bail.

Sumner was arrested in Adams on Saturday by Pittsfield Police, with assistance from Adams Police and North Adams Police. The charge is in connection with the Aug. 25 shooting on Columbus Avenue in Pittsfield, which killed 32-year-old Stephanie Olivieri.

Olivieri, of Yonkers, suffered a single gunshot wound while sitting in a silver sedan near the intersection of Columbus and South John Street. Investigators believe that Ms. Olivieri was not the intended target of the shooting.

This investigation has been led by the Pittsfield Police Department with assistance from the Massachusetts State Police Detectives assigned to the Berkshire District Attorney's Office, the District Attorney's Office, and the Berkshire County Crime Task Force.

"I send my heartfelt condolences to the Olivieri family for their tragic loss," District Attorney Andrea Harrington said.

"I am exceedingly proud of this investigation. It has been highly collaborative with excellent leadership from PPD. The tireless efforts of the investigative team in the pursuit of justice for Ms. Olivieri cannot be overstated."
