A teenager from Des Moines has been found guilty in connection with a carjacking last year.

A jury in Polk County delierated only for a short time Thursday afternoon before finding 17 year old Terrence Cheeks guilty of two counts of first degree robbery.

Cheeks and two other teens were accused of being involved in several attempts a year ago last February of trying to steal a car.

Prosecutors say the time they actually succeeded left the car's owner with permanent brain damage.

Cheecks was tried as an adult and will be sentenced June 13
