A federal judge on Friday sentenced two men to lengthy federal prison terms for a violent carjacking and robbery at a Memphis construction site in November 2024. Marterrio Armstrong, 21, received a 13-year sentence, while Jacam'Ron McIntosh, 21, of Oxford, Mississippi, was ordered to serve 8.5 years behind bars.
How Prosecutors Say the Construction-Site Ambush Went Down
Prosecutors say the case traces back to November 24, 2024, when Armstrong and McIntosh allegedly walked up on nine construction workers who were packing up at a residential job site. The men pulled guns, ordered the crew to hand over wallets, phones, and keys, and punctuated the threat with a warning: “Don't move or we will f**k you up,” according to the Department of Justice as cited by Action News 5.
How Police Tracked Them Down
Less than an hour after the holdup, Memphis police followed a signal from one victim’s cell phone to a nearby house, where officers found the stolen Nissan Maxima stashed in a carport behind trash cans. Inside, officers reported finding Armstrong along with the workers’ stolen belongings, while McIntosh was discovered hiding in the attic with a Glock 19, a Romania Arms Mini Draco, and one of the stolen wallets, according to WREG.
Court Records and Hearings
Federal court calendars show McIntosh entered a change-of-plea in March, and sentencing hearings for the case were held this week in Memphis federal court. The U.S. District Court calendar for the Western District of Tennessee lists both defendants along with the June sentencing dates; the docket spells out the case history in more detail: U.S. District Court, Western District of Tennessee.
Part of a Wider Federal Crackdown on Carjackings
The U.S. Attorney’s Office for the Western District of Tennessee has been racking up multi-year sentences in a string of carjacking prosecutions in 2026, highlighting a broader federal push on violent street crime in Memphis. For instance, the office separately highlighted another armed carjacking case that drew more than a decade in federal prison earlier this year: U.S. Attorney’s Office, Western District of Tennessee.
Armstrong and McIntosh will both serve their time in the federal system, and Western District court records show the case moving through the docket from spring into late June. Local prosecutors and Memphis police did not immediately respond to requests for comment.
