MAPLEWOOD, Mo. – Authorities are searching Tuesday morning for a teenager now charged in connection with a murder last week in Maplewood.

The Major Case Squad has been investigating the murder. Court documents detail the case leading to charges being filed against 18-year-old Justin Vance.

The St. Louis County Prosecuting Attorney’s Office has charged Vance with second-degree murder, armed criminal action, and tampering with physical evidence in a felony prosecution. Authorities told FOX 2 that at this point, Vance is not in custody and should be considered armed and dangerous.

This all unfolded last Thursday in the courtyard of an apartment building on Yale Avenue in Maplewood, not far from Manchester Road. Major Case Squad investigators have identified the man who was shot and killed as 32-year-old Terrron Vales of Maplewood.

Court documents reveal that Vance and other co-conspirators met with Vales and demanded that Vales pay them $400. When Vales refused, one of the co-conspirators got into a fight with him. Then the documents read that Vance pulled out a handgun and shot Vales in the back.

Vales was rushed to the hospital, but later died.

We’re told that after the shooting, Vance and the other co-conspirators ran from the scene. The documents read that Vance went to a nearby garage, where he hid the murder weapon. If you have any information, you are asked to call the Major Case Squad or the Maplewood Police Department at 314-645-3000. Vance’s bond has been set at $1 million in cash only.

FOX 2 will update this story with more information as it becomes available.
