4 Johnson County teenagers charged with first-degree murder in Olathe park shooting

A 13-year-old and three 14-year-olds from Olathe have been charged with first-degree murder in the fatal shooting of a 19-year-old at an Olathe park, the Johnson County district attorney announced Tuesday.

The four teenagers are charged in the killing of Marco Cardino of Smithville. Officers investigating the sound of shots being fired Saturday found Cardino suffering from multiple gunshot wounds shortly before 4 a.m. in Black Bob Park at 14500 W. 151st Street. Cardino died at the scene.

Police arrested the four teens after contacting everyone involved in the shooting, police said Monday night.

The teens, who are not being identified because they are minors, made their first court appearances Tuesday morning.

The Johnson County District Attorney’s Office has filed motions to prosecute at least three of the teens as adults. One of the them has three pending cases, two of which the defendant is alleged to have possessed a firearm.
