A late-night welfare check in Poteau turned into a homicide investigation early Sunday after officers found 53-year-old Kirk Plepla dead of an apparent gunshot wound inside a home on the 200 block of South Earl Street. His wife, 53-year-old Mollie Plepla, was arrested hours later on a complaint of first-degree murder.
Poteau police officers responded to the residence at approximately 12:42 a.m. Sunday for a welfare check, according to 5NEWS. What began as a routine check on a resident's wellbeing quickly escalated once officers discovered Kirk Plepla's body. Per KOKH, authorities say Mollie Plepla allegedly shot and killed her husband, though the case remains an active investigation and no formal charges beyond the arrest complaint have been filed.
The Poteau Police Department requested help from the Oklahoma State Bureau of Investigation to process the crime scene, while the Office of the Chief Medical Examiner was called in to conduct an autopsy and determine the official cause and manner of death, the station's report notes. Following that joint investigation, Mollie Plepla was arrested and booked into the LeFlore County Jail on the first-degree murder complaint.
Why State Investigators Got Involved
The OSBI does not simply show up on its own. Under state law, the bureau operates strictly as an assisting agency and cannot independently initiate a local homicide investigation unless formally requested by local police chiefs, sheriffs, district attorneys, or state officials, according to Oklahoma.gov. That arrangement lets smaller municipal departments like Poteau's tap into specialized crime scene technicians, ballistics experts, and crime lab services they otherwise lack in-house.
It is the same assist-only framework Hoodline detailed in its coverage of a body found near El Reno, where OSBI and the Office of the Chief Medical Examiner played similar supporting roles in an unattended death investigation. This is not the first time OSBI has assisted Poteau police on a major case, either — in March, Hoodline reported on a separate double homicide investigation in the same city that also drew state involvement.
What Happens Next in Court
Mollie Plepla remains held at the LeFlore County Jail, a facility described by Architects In Partnership as a maximum-security lockup built to house between 180 and 196 inmates and serving multiple LeFlore County municipalities, including Poteau, Heavener, and Spiro. It is important to note that an arrest on a complaint is not a formal charge; prosecutors with the LeFlore County District Attorney's Office would still need to file charges before the case proceeds to trial.
If Mollie Plepla is ultimately charged and convicted of first-degree murder, Oklahoma law lays out three possible penalties under Title 21 Section 701.9: the death penalty, life imprisonment without parole, or life imprisonment. Should a life sentence be handed down, the state's mandatory minimum service rules classify first-degree murder as an 85% crime, meaning a defendant would have to serve at least 38 years and 3 months before becoming eligible for parole. Those sentencing guidelines fall under the Sentencing Modernization Act, a law that took effect January 1 and restructured felony classifications while expanding mandatory minimum service requirements across violent crime categories statewide.
A Rare Homicide for a Small County Seat
Poteau serves as the county seat of LeFlore County in eastern Oklahoma, with an estimated 2026 population of 9,234 residents, up from 8,822 recorded in the 2020 Census, per World Population Review. Homicides are uncommon there: FBI crime data compiled by OpenCrime shows Poteau recorded zero homicides in both 2023 and 2024, while its overall violent crime rate actually fell 21.7% in 2024, dropping to 294.7 incidents per 100,000 residents.
Several key questions remain unanswered. The Office of the Chief Medical Examiner has not yet released the official cause and manner of death, the LeFlore County District Attorney's Office has not announced formal charging decisions, and no preliminary hearing date has been scheduled at the LeFlore County Courthouse. Hoodline will continue following the case as it moves through the local court system.
