FREDONIA – The Chautauqua County District Attorney’s Office says the Fredonia police officer who shot an killed a man last December will not face any charges or disciplinary action.

District Attorney Patrick Swanson held a press conference in Fredonia on Friday afternoon to announce the conclusion of his investigation into the incident that took place on December 10 at a residence on Liberty Street in the north county village.

Swanson said evidence has shown that the suspect – identified as Gueorgui “George” Penev – had already done harm to himself, with a forensic examination showing he was also under the influence of cocaine and LSD.

When officers were called to the residence on a report of a despondent individual, Penev reportedly went after Police Officer Nathan Scriven with a knife with a nine-inch blade. Scriven then exited the home and Penev followed him out and continued to approach Scriven until he was fatally shot.

An examination by the medical examiner also concluded that Penev had several self-inflicted wounds that were substantial and he would have likely succumbed to those injuries, had he not been shot by police.

The investigation not only relied on information from the medical examiner, but also body camera footage from the officers who responded.

In addition to closing the investigation, Swanson said a resident at the home, identified as Amanda Bridges, was also charged for allegedly supplying the drugs the Penev.

The Buffalo News is reporting the identity of the man who was shot to death on December 10 at 76 Liberty Street was 23-year-old George Penev.

The man’s family, from Wyoming County, had requested that his name not be released until relatives who lived outside the U.S. could be notified.

Penev allegedly went after Police Officer Nathan Scriven with a knife during the incident, which resulted in Scriven fatally shooting Penev, claiming self defense.

The Chautauqua County District Attorney’s Office is handling the case and the investigation is still ongoing.

The Jamestown Post-Journal says Chief Brad Meyers said in a press conference on Thursday that the Patrolman involved in the shooting was Nathan Scriven, a 15-year member of the Fredonia Police Department.

Scriven shot a male subject outside of 76 Liberty St. around 1:45 p.m. Monday while responding to a call of a man barricaded in a bathroom of the residence. When Scriven arrived on the scene, the male reportedly came at the officer with a knife. Scriven left the home but was followed by the knife-wielding subject and the officer eventually shot him, claiming self-defense.

Chief Meyers also said the State Attorney General’s office reviewed footage from a body camera and determined the incident did not require further involvement by the state in investigating the incident.

The Chautauqua County District Attorney’s office is now the lead agency in the investigation.

The name of the man who died has not been released.
