Expelled Waukesha North Teen Forced Way Into Classroom, Police Say

An 18-year-old man who was expelled from Waukesha North High School is accused of entering the school, causing a ruckus and threatening to kill his ex-girlfriend's friend, according to a criminal complaint.

Jordan T. Hartz was charged Thursday in Waukesha County Circuit Court with possession of narcotic drugs, carrying a concealed weapon, bail jumping, disorderly conduct and possession of drug paraphernalia. He also was charged Thursday with two count of burglary as a party to a crime in an unrelated incident.

According to the criminal complaint:

Hartz called his ex-girlfriend on Wednesday, yelling at her for blocking his phone number. The girl’s friend got on the phone to calm Hartz down, when Hartz threatened the male friend.

“I got heat,” said Hartz, according to the girl’s statement to police. “I’m gonna put a boot through your jaw.”

After the conversation finished, the ex-girlfriend went into her English class. She told the school resource officer Hartz pushed his way past the teacher who was trying to close the classroom door.

“Who the (expletive) was I talking to before?” Hartz yelled.

Other teachers came to help and Hartz ran away. The ex-girlfriend told police she was very frightened and was afraid Hartz would hurt or kill her.

The male friend told police Hartz threatened him.

“I am going to kill you, and I know where you live,” said Hartz, according to the male friend’s statement.

After Hartz left the building, a Waukesha police officer saw his vehicle after an attempt-to-locate call was sent via dispatch. Hartz had unpaid parking tickets, so the officer pulled him over for suspended registration.

The police officer located a 10-inch long hunting knife beneath the driver’s seat, syringes and other heroin paraphernalia, and a metal tin that tested positive for heroin.

Hartz told the school resource officer investigating the incident that he was angry the ex-girlfriend had blocked his phone number and his mother’s phone number. He felt that if he was with the girl, he would stop using heroin and cocaine.

When the male friend started speaking to him, Hartz told police, he was angry, threw a bathroom mirror on the floor and decided to go to Waukesha North High School.

Because Hartz was banned from the school, he flagged down another student at a side door to let him into the building. Waukesha North locks all doors and visitors have to be buzzed through the front door.

Hartz faces up to 38 months in prison if convicted in Wednesday’s incident. He also faces up to 15 years in prison if convicted of two counts of burglary as a party to a crime.

According to the criminal complaint in the burglary case:

Hartz and a juvenile broke into two homes in the 400 block of Lake Street in October. The items from the burglary were later located by the Greenfield Police Department.

Hartz told Waukesha police he and his friend stole jewelry and a video game controller from one home and 12 rings from a different home. The two individuals sold the jewelry for $850 at two separate stores.
