Woman pleads guilty in execution-style shooting of teen in Howard Co.

The third and final defendant in the Marriottsville shooting pleaded guilty on Monday in connection with the kidnapping and execution-style shooting of a 15-year-old boy in a Howard County field in 2012.

Laura Christian Karr, 26, of the 400 block of High meadow Road in Reisterstown, pleaded guilty to a kidnapping charge before Howard County Circuit Court Judge Richard S. Bernhardt, according to State's Attorney spokesman Wayne Kirwan.

Karr is the third person convicted in the shooting of the teen, who survived. She is scheduled to be sentenced Feb. 13.

Last month, Donald George Peoples Jr., 22, was convicted of first- and second-degree attempted murder and other charges by a Howard County jury. Karr testified against Peoples during his trial in exchange for a plea deal.

Peoples is scheduled to be sentenced Jan. 30.

Last July, Chiquita Sketers, 22, of Randallstown, pleaded guilty to attempted first-degree murder and a felony gun charge for her role in the abduction and shooting. She was sentenced to 25 years in prison.

According to police and prosecutors, the boy was mistakenly identified as responsible for an alleged drug rip-off deal gone bad. He was then abducted as he walked near his Reisterstown home, and forced into Karr’s 2012 Mazda, Kirwan said.

Karr, along with two co-defendants, drove the teen to Howard County, where he was ordered out of the vehicle, Kirwan said. As the boy walked away, he was shot in the back of the neck by Peoples, Kirwan said.

Karr's uncle, Ronald Cox, was shot and killed at the Reisterstown home, which the two shared, after he allegedly attacked Baltimore County police with a sword. The officer was at the home serving a warrant for Karr's arrest in the Marriottsville shooting.
