Family members have launched an online fundraising campaign to help pay for the funeral expenses of a beloved store clerk gunned down during an apparent robbery over the weekend.

Mike Ngangi, also known as Mike Mulwa, was shot about 11:30 p.m. Saturday at the Citgo in the 9800 block of Parkway East. Birmingham police Sgt. Bryan Shelton said East Precinct officers were dispatched to the store on a robbery alarm. When they arrived, they found two people consoling Ngangi, who had been shot one time.

Ngangi was taken to UAB Hospital where he underwent surgery. He died about 4:30 a.m. Sunday at the hospital.

Authorities have not announced any arrests in the case, but said it appears robbery was the motive. There were signs of a struggle inside the store. "Investigators are sure an altercation took place inside the location, and at some point the victim was shot,'' Shelton said.

A clerk was shot at the same Citgo in December, but survived. In that incident, the victim was shot with a handgun in the torso area around 9 p.m. Ngangi was working that night as well, and witnessed the shooting.

"People should be able to go to work and return home without being the victim of a crime,'' Shelton said Sunday. "Our investigators will work hard to bring this family answers and bring the killer to justice."

Family members said he told a friend by telephone that he had been shot and asked that friend to call 911. He was from Acworth, Georgia. His mother, Violent Mueni, and father, Councillor Ngangi, live in Kenya, as well as his only surviving brother, Vincent Mutuku. His cousins living in the U.S. include Erik Sukulu in California, Lilian Musyoki in Tennessee and Eunice Munyiva, in Georgia. All of his other cousins and family remain in Kenya.

He leaves behind a wife, two children and a third due to be delivered in less than one month. "Mike had the entrepreneurial spirit that guided him in his pursuit of the American dream,'' his cousin, Eric Sukulu, told AL.com. He moved to the U.S. in 2008, and worked in various department stores in Atlanta before landing a job with Shaw Industries.

"His ambition and thirst for success led him to open a cultural clothing line, "254," and he traversed the country selling his merchandise to his Kenyan-American target market during major sporting events,'' Sukulu said. "He was an outstanding citizen who knew that the path to success is a treacherous one but, step by step, one can get there through hard work and commitment."

Family described him as soft-spoken and kind - a man of the people. "His smile was contagious. He lit the room,'' his cousin said. "His demise is one that has sent waves through the Kenyan-American community.''

"If only that senseless killer knew him, he could not have pulled the trigger,'' Sukulu said. "If only he knew he just had a baby and another on the way, he could not have robbed them of their father."

A fundraiser and memorial will be held for him at KACC Church Sunday in Marietta, Georgia. Ngangi's wife, daughter and son live in Atlanta. His third child is due in three weeks. The GoFundMe link can be found here.

"Remember his family here and back home in your prayers,'' the family wrote on the site.
