(WGN-AM)- The grandson of former Chicago Defender publisher John Sengstacke was convicted of a felony weapons charge today after he was caught with a handgun last fall outside the South Side home of President Barack Obama.

Omhari L. Sengstacke, 31, of the 3400 block of South Prairie Avenue, was found guilty during a bench trial of two counts of aggravated unlawful use of a weapon by Judge Nicholas Ford and will be sentenced next month. He faces up to 7 years in prison.

In September, Sengstacke was arrested after he repeatedly tried to pass security barriers near Obama's Kenwood neighborhood home, saying he wanted to talk to the then-U.S. senator about a job.

Police found a handgun and a bulletproof vest in his car, but authorities said Sengstacke never made any threatening statements toward Obama.

Sengstacke, who has previous convictions for battery, aggravated assault, theft and forgery, is slated to be sentenced July 10.
