(MSC News)--Charges have been upgraded against a 14-year-old boy accused of shooting and killing another teenager in St. Joseph, Missouri in November.

KQ2-TV reports amended charges of involuntary manslaughter in the first degree and armed criminal action were filed Monday in juvenile court against the teen suspect.

The 14-year-old, who has not been identified because of his status as a juvenile, was originally charged with assault.

St. Joseph Police responded to a shooting on Nov. 9 near 29th and Penn Streets.

The victim, also 14, was life-flighted to Children’s Mercy Hospital in Kansas City where he later died from his injuries. The charges were upgraded after the teen’s death.

No decision has been made about whether the case will stay in juvenile court.

The next hearing is scheduled for Dec. 20.
