A Janesville man faces a felony terrorist threat charge after police say he threatened hospital staff over the phone that he’d kill them with a semiautomatic rifle.

According to a criminal complaint filed in Rock County Circuit Court, 32-year-old Brooks Riley White-Pentony called the Mercyhealth Janesville Hospital and Trauma Center emergency room last week and told staff there he needed the tranquilizer medication lorazepam.

Police say White-Pentony then told ER staff over the phone that he planned to come to Mercyhealth with an AR-15 semiautomatic rifle and kill everyone there.

According to the complaint, an officer later reached White-Pentony over the phone. White-Pentony uttered an obscenity at the officer and hung up.

He was later arrested and was released on a $500 signature bond.

A felony terrorist threat is punishable by up to three years in prison.
