PITTSFIELD, Mass. — On Friday, May 31 Tyler Sumner was found guilty of Murder in the First Degree and Possession of Ammunition without a Firearm Identification Card by a jury of his peers. 

 

The trial was held in Berkshire Superior Court; Judge Flannery will schedule sentencing.

 

Tyler Sumner, age 30 of North Adams, was found guilty of murdering Stephanie Olivieri, age 37. 

 

According to a report, in the early morning hours of Sunday, August 25, 2019, Pittsfield Police responded to 911 call reporting two masked men walking around 66 South John Street. 

 

While in route, the responding officers heard several gun shots around the area of South John Street. When the officers arrived on the scene, they found a woman, later identified as Stephanie Olivieri, in her running car. Olivieri was gasping for breath and had blood running down the right side of her head. 

 

The responding officers called for backup and began lifesaving efforts. Olivieri was treated by EMS on the scene and then transported to Berkshire Medical Center where she was later pronounced dead. The Chief Medical Examiner found the cause of her death to be a homicide caused by wounds sustained from a bullet to her head.

 

Multiple individuals testified that they believed Tyler Sumner was targeting an individual living in the area of the shooting. They believe that Olivieri was not the intended target of the murder.
