According to Chicago Police, Muhammed got into an argument with three men before being shot in the head.
The shooting happened early Saturday morning at 2145 South Pulaski. Surveillance video may help police solve the crime.
It's still unclear what sparked the attack that claimed the life of Nawez Muhammed. His heartbroken family says the 28-year-old was a dedicated husband and father whose first and only thought was of his family. He worked tirelessly at the family's restaurant to provide a good life.
"He's always working. He always cares about his kids," said Faisal Bilar, Muhammed's relative.
Witnesses tell police Muhammed was gunned down early Saturday morning as he worked at his West Side restaurant. Investigators say Muhammed stepped outside his establishment for some reason and got into an argument with several men.
Detectives say the verbal altercation escalated to a physical scuffle. Then one of the men involved in the fight pulled out a gun and shot Muhammed in the head.
Saturday afternoon, the neighborhood remains quiet about the incident as police look into the possibility Muhammed's death was the result of a botched armed robbery. Friends say the restaurant owner hadn't spoken about having any problems in the area and he often kept his business open even into the early morning hours.
Police are hoping images from a surveillance camera on the building where Muhammed's restaurant was will help lead them to a suspect.
No arrests have been made.
