A months-long investigation into a deadly roadside shooting near Linton has ended with no charges against the man who pulled the trigger. Greene County Prosecutor Jarrod Holtsclaw announced that Steven Couch was justified in shooting Lowell “JR” Harroll at around 9:30 p.m. on August 6, finding that Couch acted in self-defense and in defense of his wife after Harroll pursued their vehicle on State Road 59 and tried to run them off the road.
According to the Vincennes Sun-Commercial, Harroll had arrived at the Linton Walmart shortly before the shooting and appeared to notice Carol Couch’s vehicle parked in the lot. Investigators determined he went inside the store and appeared to be looking for someone before making a purchase, then seemed to notice Carol leaving with Steven Couch in Steven’s vehicle. Surveillance footage reviewed by investigators showed Harroll pursuing the couple’s vehicle south through Linton on State Road 59 shortly afterward.
Once on the highway, the investigation found, Harroll passed the Couch vehicle and pulled over, then caught up to it again, tailgated it, drove erratically and at one point attempted to run it off the road before passing it a second time and pulling over. He then exited his vehicle and approached the Couches on the highway. Steven Couch opened the driver’s door and allegedly told Harroll to stop before firing four rounds from a 9mm handgun, striking Harroll twice. Scene measurements indicated Harroll was between five and six feet from Couch when the shots were fired.
Investigators Pieced Together the Chase With Cameras and Phones
Couch called 911 immediately after the shooting and told dispatch that Harroll had pursued his vehicle, passed it, pulled over, exited and approached his car, per the newspaper’s account of the investigation. Officers found Harroll lying along the edge of the highway south of Linton; he was taken to Greene County General Hospital, where he was later pronounced deceased.
The investigation drew on the Greene County Prosecutor’s Office, the Greene County Sheriff’s Department, the Linton Police Department and the Indiana State Police. Investigators interviewed Steven and Carol Couch, drivers who encountered the vehicles on State Road 59, and people close to both Harroll and the Couches. They also collected surveillance video from locations around Linton, acquired Flock camera data to build a timeline and verify accounts, gathered cell phones from Harroll and the Couches for examination, and executed search warrants for social-media accounts belonging to all three.
An Indiana State Police crime scene technician processed the shooting scene, collecting the firearm, shell casings, photographs and measurements. A separate report from Yahoo News notes that a Flock license-plate-reader camera sits on Indiana 54 near the Linton Walmart, part of a 20-camera, five-year contract Greene County approved with Flock Safety in January 2025. The same report notes the system, which generated 65 searches by county investigators during the second quarter of 2026, can provide investigators with quick location data and help sort out conflicting accounts in cases like this one.
Autopsy Found Severe Meth Toxicity and Low-Level Alcohol
An autopsy performed on August 11 by Dr. James M. Jacobi found Harroll suffered two gunshot wounds — a pass-through wound to his right arm and a wound to the right side of his back. Jacobi determined the cause of death was a liver perforation with a graze wound to the kidney. The autopsy also found severe methamphetamine toxicity, with a level of 4,147 ng/mL, along with a blood-alcohol content of 0.031%, according to the Sun-Commercial’s reporting on the prosecutor’s findings.
Investigators also laid out the two men’s criminal histories as part of the case file. Harroll had an extensive record that included 20 prior convictions, among them felony intimidation, resisting law enforcement and five separate battery convictions. Couch, by contrast, had a single Class C misdemeanor conviction dating back to 1994. The prosecutor’s announcement also noted that Carol Couch and Harroll had recently ended a relationship that a press release described as stormy, involving alleged physical abuse and threats.
Prosecutor Cites Indiana’s Self-Defense Statute
Holtsclaw’s office determined that Couch was justified under Indiana law in shooting Harroll to protect himself and his wife from serious bodily injury while inside their vehicle. Indiana Code 35-41-3-2 permits deadly force without a duty to retreat when a person reasonably believes it necessary to prevent serious bodily injury, death or a forcible felony, and separately allows reasonable force, including deadly force, to prevent or end an unlawful attack on an occupied motor vehicle. Based on those findings, the prosecutor’s investigation resulted in no criminal charges being filed against Steven Couch.
The case echoes another Indiana road-rage shooting resolved without charges earlier this year. In Hancock County, the prosecutor’s office determined in late July that a Volkswagen driver acted within the state’s self-defense law after reviewing witness statements, video recordings and forensic evidence, according to WRTV. Both cases involved video evidence; the Greene County investigation also drew on phone records and camera data, which investigators say are increasingly central to sorting out what happens in fast-moving confrontations on Indiana roads.
