Elahmadi Goba was the type of guy to spot you a buck if you were short.

The 40-year-old convenience store clerk known for letting customers even up on the bill on the next visit was found dead around 7:40 p.m. Tuesday, shot inside the N&A Food Market, police said. Investigators and one of the store’s owners said there was no evidence that the shooter had stolen anything from the store. Two bullet holes were shot through the counter’s Plexiglas barrier, said N&A part-owner Naji Saleh.

Saleh was reviewing video surveillance tape Wednesday afternoon to look for any evidence of the shooting. Police had no one in custody Wednesday afternoon.

“He’d laugh and joke with you, and he was real good with the kids,” said Latricia Harlan, 41, of Goba. “I can’t see nobody doing this to him.”

Saleh described Goba as a “friendly guy,” who had worked at the store for about two months.

Goba, of the 500 block of East 79th Street, moved to Chicago from out of state after emigrating from Yemen, said Bill Shilwa, whose cousin owns the convenience store. Shilwa said Goba’s family was traveling to Chicago after hearing about his death.

One neighbor, who declined to give her name, said she heard five shots while she was watching “Dancing With the Stars.”

“It sounded like a small cannon. Even with my bad hearing and the TV, I heard it,” she said.

The convenience store is just a short stroll from Paul Cuffe Academy, a Chicago Public Schools elementary school.

JoAnne White was walking her granddaughter, Naleia Roberts, to that school Wednesday, when they stopped to leave a Tweety Bird stuffed toy and a candle outside the convenience store.

“It’s totally horrible,” said White, a regular customer. “This is our neighborhood. They were good people. It was the only close store in the neighborhood. They were really great guys. They tried to help you in any way they could.”
