In the quiet rural landscape of Grant County, Wisconsin, the night of March 19, 1990, brought a sudden and violent end to the life of 39-year-old Thomas L. Reuter, a White male and a respected Deputy Sheriff. On what began as a routine patrol, Reuter, a 13-year veteran of the Grant County Sheriff's Department, was heading home after his shift around 11:20 p.m.
His attention was drawn to a tractor on New California Road, about two miles south of Livingston, which he radioed in as a disabled vehicle at 11:24 p.m. This would be his final communication.
The operator of the tractor was 18-year-old Gregory Coulthard, a local farmhand who was on probation and had a suspended driver's license. After consuming alcohol earlier in the day, Coulthard had decided to take the tractor, armed with a 12-gauge shotgun, to visit his girlfriend in Platteville. Frustrated for reasons that remain somewhat unclear, he had already fired the shotgun at a billboard before turning back. When Deputy Reuter pulled up behind him with his emergency lights activated, Coulthard, fearing a return to jail, made a fateful decision. As Reuter approached the tractor, Coulthard fired the shotgun, fatally wounding the deputy. When dispatch could not get a response from Reuter, a search was initiated, leading to the discovery of his body in a nearby ditch.
The investigation swiftly led to Gregory Coulthard, who was apprehended by a Dane County K-9 unit about five hours after the shooting, five miles from the scene. He was charged with first-degree intentional homicide. During his trial in July 1990, his defense attorneys argued that the shooting was not intentional, aiming for a lesser charge of first-degree reckless homicide. However, a key moment in the trial came during cross-examination when Coulthard was asked, "When the officer came around, that's when you shot him, is that correct?" He replied, "I shot him when I saw him," a statement the prosecutor later called "the truth finally coming out of his mouth."
The jury, brought in from Waukesha County to ensure a fair trial, found Gregory Coulthard guilty of first-degree homicide. He was sentenced to life in prison with the possibility of parole after 25 years. The murder of Deputy Thomas L. Reuter, a husband and father of five, sent shockwaves through the small community, a stark reminder of the dangers faced by law enforcement officers. His death was a profound loss, and the subsequent legal proceedings brought a measure of justice for a life cut tragically short in the line of duty.
