ST. LOUIS (KTVI) -There were big developments Wednesday in one the saddest murder cases the St. Louis Circuit Attorney said she'd ever seen.
Christopher Grant, 18, of Collinsville, was charged with 1st degree murder plus weapons and attempted robbery charges; 6 counts total.
It all played out near Europe Night Club on 15th Street, January 11th in downtown St. Louis.
Grant walked up on a car to commit a robbery and coldly shot Bobby Christman, 19, of Oakville, when Christman tried to intervene, authorities said.
Christman was in the passenger seat of the car. His younger brother was driving. A female friend was in the back seat.
Mr. Grant got out of his car, approached the car the victim was in, displayed a gun and ordered everybody out of the car," St. Louis Circuit Attorney, Jennifer Joyce, said.
"At that point, he opened the driver's side door … he reached in to grab the purse of the young woman in the back seat…the victim (Bobby Christman) tried to intervene…as soon as he did that Mr. Grant shot the victim in the head and he died…Mr. Christman's brother was driving the car. He ducked down a little bit," Joyce said.
Grant was locked up in the St. Clair County jail on unrelated charges.
Illinois State Police picked him up in the past day or two on outstanding warrants for battery and illegal possession of alcohol.
Two other suspects are in the same jail on unrelated charges. Aza Thompson, 18, and Tony Ross, 19, have yet to be charged in the Christman case.
Christman was a DeSmet High School graduate and student at Southeast Missouri State.
He was still home on holiday break, shot dead in front of his little brother, allegedly by another teenager.
"It's hard to imagine a sadder case than when you have someone so young killed by someone who is 18-years-old," Joyce said.
Grant will be extradited to Missouri to face the murder charge.
Grant remains jailed on $1 million cash-only bond.
