Two men have been charged with attempted murder after police say they stabbed a man multiple times and slashed him with a medieval battle ax.

Early Tuesday morning, Cody Jesse Augustine and Scott Tyler Stapley, both 21, attacked a 17-year-old boy outside his home near 4500 West and 5780 South, according to charges filed Thursday in 3rd District Court.

According to jail documents, Augustine said he was jealous of the victim text-messaging a girl and believed he had contracted a sexually transmitted disease from the girl that she got from the victim.

Augustine slashed and stabbed the victim several times with a knife, and Stapley slashed the teen's shoulder with a "four-bladed warrior-style ax," according to the charges.

The victim suffered life-threatening injuries from the attack, including a deep cut on his neck that required more than 300 stitches and staples, the jail documents state.

Police said Augustine and Stapley are affiliated with Juggalos, who are fans of the rap group Insane Clown Posse. The group has been classified as a gang because of a continued pattern of criminal activity, police said.

A necklace of a "hatchet man" left at the scene of the attack and a bumper sticker depicting the same Juggalo image were the keys to finding the attackers, police said.

Both men face charges of attempted murder with injury, a first-degree felony.
