Update – The man killed in this shooting has been identified as Darin Gosejohan.

ST. CHARLES COUNTY, Mo. – An overnight shooting at a St. Peters home leaves a man dead and two others hurt. The Major Case Squad has been activated to investigate the case Monday morning. Authorities tell FOX 2 that there are no suspects in custody. This all unfolded at a home in the Country Creek Subdivision on Country Acres Drive, not far from Jungerman Road.

Police crime scene tape is up around much of the home. We’re told the case is being treated as a homicide. Police at the scene have been focusing a lot of attention on the front door area of the house.

Sergeant Melissa Doss with the St. Peters Police Department told us authorities received a call for a shooting at the home around 1:30 a.m. Upon arrival, police found the troubling scene.

Doss said a Gosejohan, 57, was found dead inside the home from an apparent gunshot wound. Two female victims, 13 and 45, were also inside the house were shot as well. The three people shot are related.

Doss explained that they were taken to a hospital with non-life-threatening injuries.

Fairmount Elementary School is very close to the scene. There are also many other homes nearby.

FOX 2 spoke with several neighbors throughout the morning. All of them were stunned – some a little frightened by what happened.

They told FOX that a husband and wife lived in the home with their two younger children and perhaps one other family member.

We spoke with a neighbor about his reaction to crime scene tape and multiple police vehicles in his normally quiet subdivision.

“It’s more shocking than scary,” Andrew Nevenner expressed. “It’s something like I said that’s completely abnormal than what I’m used to. I grew up and went to the school at Fairmount Elementary right here when I was younger – and I mean I’ve walked up and down this street coming home from school after sports or whatnot and choir and I just never would have thought something like this would have happened.”

In addition to St. Peters Police, St. Charles County Police have also been at the scene with their crime scene unit and forensics team.

A Francis Howell School District spokesperson told FOX 2 that because of the shooting, Fairmount Elementary – the school very close to the scene, is in a “heightened awareness” status.

That means the students will remain indoors until the status is lifted.

All outdoor activities are canceled for Monday at the school, including “Field Day.”

That has been rescheduled for Thursday.

At this point, police have not released the name of the person who was killed. FOX 2 will update this story with more information as it becomes available.
