Indiana State Police are investigating an officer-involved shooting and a separate homicide that occurred early Saturday morning in Lawrenceburg.

According to the Versailles ISP Post, the investigation began when police were called to the Summit Pointe Apartments located on Deer Run Drive in Lawrenceburg in reference a disturbance at about 3 a.m. Saturday.

The first officer arrived shortly after the call was dispatched and upon entering the apartment building the officer was confronted in the hallway by Brandon G. Evans, 33, who was naked and holding a knife. The Lawrenceburg officer fired at least one round from his department handgun, striking Evans.

The officer was not injured and, along with other officers from the Lawrenceburg Police Department, Dearborn County Sheriff’s Office, and Greendale Police Department, attempted to administer first aid before Evans died from his injuries.

Evans was pronounced dead at the scene by the Dearborn County Coroner’s Office.

While canvassing the apartments, officers located Staci L. Coyne, 37, dead inside one of the apartments. The investigation determined that Coyne was the victim of a homicide and she was also pronounced dead at the scene by the coroner’s office.

Investigators believe the two incidents are connected and that Evans and Coyne knew each other. Detectives also discovered that Evans had allegedly entered a different apartment in the building and caused damage inside the unoccupied apartment prior to officers arrival on scene.

The Lawrenceburg Police Department requested that detectives from the Indiana State Police-Versailles Post respond and conduct an investigation into the incident.

The investigation is ongoing at this time. Autopsies were scheduled to be performed Monday in Hamilton County, Ohio. The involved LPD Officer’s name will be released at a later date. At the conclusion of the investigation, the case will be forwarded to the Dearborn County Prosecutor’s Office for review.

The Indiana State Police was assisted by the Lawrenceburg Police Department, Dearborn County Sheriff’s Office, Greendale Police Department, Dearborn County Prosecutor’s Office and Dearborn County Coroner’s Office.
