Two Oklahoma City men have been handed federal prison sentences totaling more than nine years for their involvement with illegal ammunition and a pipe bomb. Caleb Graves, 33, and Robert Allen Keefe, 25, faced the consequences of multiple charges related to unlawful possession of destructive devices and ammunition, as announced by U.S. Attorney Robert J. Troester.
Graves and Keefe's legal troubles intensified following traffic stops that led to the discovery of the explosive materials. Graves, who was already a convicted felon, found himself charged in November 2024 with illegal possession of ammunition and faced additional charges in April, which included possession of an unregistered destructive device. Keefe was also charged in relation to the same device, as reported by the U.S. Attorney’s Office. Details from public records indicate that a loaded firearm magazine was in plain sight during Graves' traffic stop on August 18, 2024, leading to an ATF-executed search warrant the next day where more ammunition was found.
The situation escalated when Graves got re-arrested on October 14, 2024, with an Oklahoma City Police Department traffic stop uncovering a hidden pipe bomb in his vehicle. Keefe, the sole passenger, was arrested alongside Graves. Their history includes previous felony convictions for second-degree burglary, possession of methamphetamine, and child neglect, which have contributed to their current situation.
After pleading guilty, U.S. District Judge David L. Russell decided to sentence both men in the current month, handing Graves 72 months and Keefe 37 months behind bars. According to the press release, Judge Russell highlighted the gravity of their offenses, articulating the need "to provide just punishment" in the announcement of their sentences. The bureau of Alcohol, Tobacco, Firearms and Explosives, alongside the Village Police Department and the Oklahoma City Police Department, played critical roles in the investigation that led to the duo's capture and subsequent sentencing. The case was prosecuted by Assistant U.S. Attorney Drew E. Davis, as cited by official documents.
Both individuals are also set to serve three years of supervised release following their imprisonment.
