PITTSFIELD, Mass. — An Adams man has been charged in the murder of 32-year-old Stephanie Olivieri of Yonkers, N.Y.

 

Tyler Sumner, 25, 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 that killed Olivieri.

 

Olivieri, a native of Pittsfield, suffered a single gunshot wound while sitting in a silver sedan near the intersection of Columbus and South John Street in the early morning hours that Sunday. Investigators do not believe that Olivieri was the intended target of the shooting.

 

This investigation has been led by the Pittsfield Police Department with assistance from the state police detectives assigned to the Berkshire 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."

 

Olivieri attended the former St. Joseph's High and Pittsfield High and left her parents, a brother and two young children. Her family has started a GoFundMe.
