A man in Kansas City, Missouri is facing serious criminal charges after allegedly running a car fraud scheme on Facebook Marketplace that left multiple buyers out thousands of dollars.
Mamadou Diallo, 24, was arrested and charged with 14 felony counts after authorities say he sold vehicles to buyers online and then stole the cars back shortly after the sales. Prosecutors say Diallo defrauded at least eight victims out of more than $24,000 with the repeated scheme.
Police say that between May and June 2025, several people reported that a car they bought through Facebook Marketplace had been stolen soon after the sale. In all these cases, Diallo met each customer personally and provided what looked like legitimate documents, such as titles and bills of sale, thus making him appear to have transferred each car legitimately.
The cars were again reported stolen within hours or even a few days, and it is the individuals who lose both the cars and the money they paid for them. Court records show Diallo used an online alias to post the ads and then denied involvement when detectives interviewed him.
Diallo is charged with:
Six counts of first-degree tampering with a motor vehicle
Eight counts of forgery
If convicted on all counts, he could face up to 98 years in prison, a reflection of how seriously prosecutors treat repeated schemes involving fraud and vehicle theft.
He remains in custody on a $30,000 cash-only bond, and holds from sheriffs’ offices in three other counties. Court records also show he has faced other charges in 2025 related to vehicle tampering, motor vehicle theft, and fleeing from police.
Cases like this demonstrate the risks associated with purchasing valuable items online, especially through P2P sites like Facebook Marketplace. Police and prosecutors warn internet consumers to be extra cautious by doing the following:
Verifying a seller’s identity and documentation
Checking a car’s title and VIN independently
Meeting sellers at a public location, such as at a police station
Being cautious when the deal is overly attractive
