Sparta police release more details about an officer-involved fatal shooting that occurred on October 4.

Sparta police were called to 1008 S. Fairway Drive at about 9:15 p.m. Friday for a disturbance call.

The caller told police John Bartholomew, 21, of Sparta, had been drinking and was argumentative. After the call was made, Sparta police say Bartholomew armed himself with knives and started threatening the caller and another family member.

Sparta Police Sergeant Booker Ferguson was the first to arrive on scene. When he got out of his squad car, Bartholomew started walking toward him, according to the police report. Sgt. Ferguson told Bartholomew to drop the knives, but he did not and continued to advance towards the officer. Sgt. Ferguson then fired his handgun, striking Bartholomew.

Sparta police say additional officers arrived shortly after the shooting and started administering first aid until Sparta Area Ambulance Service members arrived to help. Bartholomew was transported to Mayo Clinic Health System in Sparta and later died from injuries from the shooting.

The Wisconsin Division of Criminal Investigation (DCI) is investigating the shooting along with Sparta police and the Wisconsin State Patrol.

Sgt. Ferguson is a 10-year veteran of the Sparta Police Department. He has been placed on standard administrative leave while the investigation continues.
