A disagreement over a locksmith's bill in South St. Louis ended with two men shot and, nearly two years later, a 15-year federal prison sentence. Donnel Trotter, 51, was sentenced Monday after pleading guilty in July 2026 to one count of being a felon in possession of ammunition, stemming from a shootout that left him and the locksmith wounded on a residential block in the Mt. Pleasant neighborhood.
The U.S. Attorney's Office for the Eastern District of Missouri announced the sentence on Monday, closing out a case that began on November 12, 2024, when a locksmith was dispatched to an alley behind the 4700 block of Nebraska Avenue to unlock Trotter's truck, according to KTTN. The incident occurred around 9:45 a.m. in the Mt. Pleasant neighborhood, a residential section of South St. Louis centered around Nebraska Avenue, as previously reported by Hoodline.
A Payment Argument Turns Into Gunfire
The two men argued over payment for the locksmith's work, and Trotter moved toward the locksmith while reaching for his gun, per the station's report. The locksmith, a 20-year-old man, shot Trotter first, and Trotter returned fire as the locksmith retreated, continuing to shoot even as the younger man tried to get away.
Both men were wounded in the exchange. The locksmith fled the alley and contacted police, who later located Trotter seeking medical treatment at a hospital, the same account notes. Trotter sustained a gunshot wound to his back and initially refused to answer officers' questions once he arrived for treatment, a detail Hoodline reported in its original coverage of the shooting.
Investigators recovered two 9mm shell casings matching the locksmith's firearm and twelve spent .40-caliber shell casings at the scene, according to the same report. The locksmith himself was treated for a gunshot wound to his arm and was found in possession of a handgun that had been stolen out of Illinois, Hoodline's initial reporting on the incident showed.
Prior Felony Record Triggered a Mandatory Minimum
Trotter's status as a convicted felon barred him from possessing firearms or ammunition in the first place. Assistant U.S. Attorney J. Christian Goeke, who prosecuted the case, filed a federal sentencing memorandum detailing a criminal record dating back to 1993 that included three prior federal convictions for serious drug offenses, according to the Department of Justice.
Those prior convictions made Trotter an armed career criminal under the federal Armed Career Criminal Act, codified at 18 U.S.C. § 924(e). Under that law, a defendant with three prior convictions for violent felonies or serious drug offenses faces a mandatory minimum of 15 years in federal prison without parole, with no judicial discretion to go lower, according to the Federal Criminal Attorneys. Prosecutors argued Trotter used the ammunition in connection with a crime of violence, further triggering the enhanced penalty.
Case Fits a Broader Federal Push in St. Louis
The St. Louis Metropolitan Police Department and the FBI investigated the case before it was handed to federal prosecutors. It was brought under Project Safe Neighborhoods and Operation Take Back America, Department of Justice initiatives that pair federal agents with local police to prosecute repeat violent offenders in federal court rather than state court, where sentences and parole rules often differ.
The Eastern District of Missouri has historically ranked among the top federal districts nationwide for per-capita firearm prosecutions, a pattern that helps explain why cases like Trotter's end up federalized rather than handled locally. That tendency has only intensified recently: in August 2026, the Bureau of Alcohol, Tobacco, Firearms and Explosives launched an enforcement surge in St. Louis, pairing extra federal agents with local detectives to target illegal firearms and violent offenders, according to the ATF.
Mt. Pleasant has continued to see gun violence since the 2024 shooting. In April 2026, another double shooting occurred in the neighborhood, in the 4500 block of Pennsylvania Avenue, leaving two more men wounded, as Hoodline previously reported. Local community groups have repeatedly called for increased police patrols in the South City neighborhood.
