Jennings Felon Sentenced to 13 Years in Prison for Shooting at Ex-Girlfriend

ST. LOUIS - U.S. District Judge Joshua M. Divine on Wednesday sentenced a convicted felon who shot at his ex-girlfriend and triggered a police standoff to 13 years in prison.

Judge Divine also ordered Jairell Allmon to pay a $2,000 fine.

On Feb. 18, 2025, Allmon fired a shot at his ex-girlfriend after spending the night in her car, which was parked outside her house in Jennings. The victim told police that Allmon made threats against her and her children throughout the night, and in the morning threatened to shoot her if she tried to get in her car. He fired a shot at her but missed. When St. Louis County Police Department officers arrived, Allmon refused to reply or comply when officers ordered him out of the vehicle, triggering a three-hour standoff. After it ended, police found a 9mm handgun in the trunk of the car, which was accessible from the inside of the vehicle. Allmon is a convicted felon and is thus barred from possessing a firearm.

This is Allmon's fourth conviction involving a firearm and third involving the possessing and brandishing of a gun, Assistant U.S. Attorney J. Christian Goeke wrote in a sentencing memo, adding that the crime was one of a long string of domestic crimes.

Allmon, 40, of Jennings, Missouri, pleaded guilty in January to one count of being a felon in possession of a firearm.

The St. Louis County Police Department, including the Tactical Unit, the Crisis Intervention Team, Crisis Negotiation Team and Special Response Team, handled the case. Assistant U.S. Attorney J. Christian Goeke prosecuted the case.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces and Project Safe Neighborhood.
