CANTON, S.D. (AP) — A teenage student charged with attempted murder in the shooting of a South Dakota high school principal has hired a private investigator to help in his defense.

The Argus Leader reports that a motion filed by the defense team for 16-year-old Mason Buhl shows an investigator has been hired to locate and interview witnesses.

Buhl is charged as an adult on one count each of attempted murder and the commission of a felony while armed with a firearm. He is accused of confronting Harrisburg High School Principal Kevin Lein with a handgun in his office Sept. 30 and firing a single shot that left the principal with a flesh wound.

Buhl's attorney didn't immediately return a call from the newspaper seeking comment.

Buhl is being held without bond.
