A 36-year-old clerk at a Bensenville convenience store was killed in a possible robbery attempt Sunday night.

Along a busy roadway just west of O'Hare International Airport, Hussein Saghir appeared to try to reason with two robbers before he was fatally shot, according to a disturbing surveillance video released Tuesday.

Saghir and his brother — who owns Sam's Tobacco and Food Mart in the 200 block of West Irving Park Road in Bensenville — were locking up the store for the night at around 6 p.m. Sunday when men approached them, police said.

After about ten seconds, one of the men pulled out a pistol and pointed it at Saghir, gesturing to the blue plastic bag he was carrying, the video shows. The gunman is shown firing a shot that misses Saghir at nearly point-blank range. Just yards away, cars passed by as the confrontation played out in view of the store's security camera.

Authorities released a portion of the tape on Monday in hopes that it might lead to some information about the gunman and his accomplice. The video was edited to remove the subsequent shot that fatally wounded the Chicago man as his brother stood by helplessly, authorities said.

“We're hoping someone recognizes who these individuals are,” Bensenville Police Chief Frank Kosman said at a news conference. “This is a terrible incident.”

The confrontation lasted about three minutes, Kosman said. Saghir is seen walking out of the store, holding a blue bag when confronted.

In the video, one of the men is wearing a maroon Abercrombie and Fitch hoodie and True Religion jeans; the second suspect wears a black hoodie with a white section on the front.

The two robbers fled east on foot. Saghir, 36, was pronounced dead Sunday night at Elmhurst Memorial Hospital, Kosman said. Police have classified the incident a homicide, not an armed robbery because the suspects did not get away with anything. It was the village's first homicide in a decade, officials said.

A man who answered the door at an Arcadia Terrace address linked to Saghir said the clerk's family declined to comment. A small group of people were gathered inside, speaking quietly.

“It's a very difficult situation,” the man said.

Some of those who work near the food mart said the shooting has left them fearful.

Delfina Flores, 47, manages a laundromat next door to the convenience store. She did not know the slain clerk, but heard about the slaying when she came to work Monday.

“Oh, my God, I was so surprised when the (owner) told me what happened,” she said. “It's scary for me, because I sometimes work at night.”

David Jaeck, 68, lives near the store, but said he suffers from hearing loss and didn't hear any gunfire.

“You hear about these things all the time but it's so hard to believe so close to home,” said Jaeck, who lives in an apartment located behind the store. “It's not going to change what I do,” he said about the shooting. “All the man was trying to do was trying to work. It's a crying shame.”

In November, three men robbed the same shop, but Saghir was not working at the time, Kosman said. Police would not say how much cash the robbers got away with in that incident, which has not been solved.

In Sunday's shooting, the robbers never entered the store.

The Bensenville Police Department and the DuPage County Major Crime Task Force are investigating.
