A Buffalo man with two previous felony convictions faces up to 25 years in prison after he was convicted Monday of second-degree criminal possession of a weapon and false personation before Erie County Court Judge Michael Pietruszka, District Attorney Frank A. Sedita III said.

Tito M. Roosevelt, 32, also known as Samuel Gamblin, was arrested Dec. 3, 2011, in the Corner Store on Genesee Street, after video surveillance showed him trying to hide a stolen loaded .38-caliber pistol in a cardboard box when police officers entered the store.

Prosecutors said Roosevelt admitted to police he had come to the store to shoot a man he suspected of shooting his brother a week earlier. Roosevelt was convicted of second-degree burglary in 2001 and first-degree attempted robbery in 2005. Sentencing was scheduled for Feb. 25.
