A gas station clerk in St. Louis is charged with killing a customer he mistakenly believed stole a $1.10 bag of candy.

Taleb Rebhi Ali Jawher, 39, was charged Wednesday with first-degree murder and armed criminal action for the Sept. 26 ordeal that left 34-year-old Christopher Simmons dead, the St. Louis Post-Dispatch reports.

Simmons was gunned down outside of a Phillips 66 gas station on North Florissant Avenue in the city’s Old North St. Louis section at about 9 p.m., after Jawher followed him outside during a spat about the alleged shoplifting, police said. The pair got into another argument and Jawher shot Simmons in the back of the head as he walked toward his car, according to the charges.

Simmons “did not steal or leave the store with candy,” according to court documents cited by the newspaper.

Simmons’ mother, Dorothy Simmons, said her family is now “trying to find some peace” after her son’s death.

“He was a wonderful young man who was taken from us too soon,” Simmons, 67, told the Post-Dispatch.

Simmons told KMOV that she was relieved that Jawher has been charged in the shooting.

A judge in St. Louis set bail for Jawher, of Ferguson, at $1 million cash.
