WESTPHALIA — A Freeburg man faces two felony assault charges and a misdemeanor trespassing charge after allegedly striking two people during a party at a Westphalia residence.

Kaden Ryan Herzing, 18, was charged on Oct. 1 with two counts of third-degree assault, both class E felonies, and one count of first-degree trespassing, a class B misdemeanor. The complaint, filed by Osage County Prosecuting Attorney Amanda Grellner, alleges the offenses occurred on Sept. 25.

Judge Sonya Brandt set bond at $35,000 cash or surety, with conditions restricting contact with the victim and possession of weapons.

According to a probable cause statement from Osage County Sheriff’s Deputy D. Haslag, the investigation began on Sept. 28 when a woman reported an assault that occurred during a party at a residence in Osage County. The complaint identifies the location as a residence on CR 503 in Westphalia.

The woman told Haslag that Herzing arrived uninvited, appeared agitated, and made malicious comments about her deceased siblings. She said she responded, and Herzing became violent.

A second alleged victim, a man, took her inside the residence to separate them, according to the statement. The woman said Herzing followed them inside, where the man stood in a hallway to keep Herzing away from her, and attempted to calm him.

The man told Haslag that Herzing rammed his shoulder into his chest and, when he did not move, struck him in the left eye with a closed fist. He said he struck Herzing only after being hit, and the two became involved in a physical struggle.

According to the statement, the homeowner and another person separated them. The woman said she then pointed toward the door and told Herzing to leave, at which point he allegedly struck the left side of her face with a closed fist.

Others restrained Herzing, and the woman was taken outside and placed in a locked truck to keep him away from her, according to the statement. She told Haslag that Herzing continued acting aggressively toward others and spoke about possessing a firearm before leaving about 15–20 minutes later.

The homeowner also told Haslag that he witnessed Herzing strike both alleged victims. He said Herzing went outside after being told to leave but continued trying to confront the man before leaving the property.

Haslag reported that the homeowner provided video footage showing the physical struggle, the parties being separated, and Herzing striking the woman with a closed fist after she told him to leave.

Both alleged victims provided written statements and allowed Haslag to photograph their injuries. Haslag documented swelling and redness on the left side of the woman’s face and bruising around the man’s left eye and on his right knuckles.

The woman reported head pain and intermittent blurred vision in her left eye. According to Haslag, she went to a hospital and provided medical records documenting mild orbital swelling.

In support of requesting a warrant, Haslag cited concerns that Herzing posed a danger to the woman or the community. The woman told Haslag that Herzing knew where she lived, had expressed feelings for her, and had admitted unlawfully discharging a firearm at a store in Vienna because she entered a relationship with her ex-boyfriend. Haslag also stated that Herzing had been known to become extremely intoxicated and discharge firearms. Based on those circumstances, Haslag wrote that he believed Herzing had an extreme obsession with the woman and would become a danger to her or the community.

Court records show Herzing began five years of supervised probation on Sept. 21, four days before the alleged assaults, after receiving suspended imposition of sentence on charges of unlawful use of a weapon by exhibiting and first-degree property damage, both class E felonies. Those charges stemmed from offenses dated Sept. 21, 2025, investigated by the Vienna Police Department.

The probable cause statement lists Herzing’s arrest as Sept. 30 at 10:12 a.m. An Osage County dispatch notice records the arrest warrant as served Oct. 1 at 10:51 a.m., while he was already in custody.

Special bond conditions prohibit contact with the victim, the victim’s children, or the victim’s family without prior written court approval. Herzing must surrender all weapons to the sheriff’s office within 24 hours of release, observe a 10 p.m. to 6 a.m. curfew with exceptions for employment or medical or drug treatment, and obtain and maintain employment.

Herzing is scheduled for a bond appearance hearing at 10 a.m. Tuesday, Oct. 6, before Judge Sonya Brandt in the Osage County courtroom.
