CASPER, Wyo. — A Natrona County man who was facing two charges of Aggravated Assault, as well as a charge of Strangulation of a Household Member from an incident in late August, has been recommended for an additional Aggravated Assault charge in a June incident where he was alleged to have pistol-whipped the victim.
33-year-old Matthew Ross Drengenberg was originally arrested following the events of the August 27 incident, where he was alleged to have threatened to kill another person, kicked them, and beat them. It was further alleged that Drengenberg had dragged the victim through cactus.
Drengenberg made his initial appearance in Natrona County Circuit Court on August 28th, where he was originally charged with two counts of Aggravated Assault and Strangulation of a Household Member, in relation to the August 27 incident.

An amended affidavit, filed in Circuit Court on September 3, now alleges that Drengenberg also pistol-whipped the same victim, in an incident in June of 2019. The suspect has been recommended for an additional Aggravated Assault charge in that incident.
Natrona County Sheriff’s Office investigators say that the alleged victim in the case reported an incident at the end of June 2019, where Drengenberg pulled a handgun out and used it to physically strike the victim. The accuser suffered an open head wound, and was eventually treated at the hospital for the injury. The victim, however, told law enforcement that they had not previously reported the incident.
According to officials from the Natrona County District Attorney’s Office, Drengenberg was released on bond during both the June and August incidents. Court records show that Drengenberg was arrested by the Casper Police Department, in April of 2019, on a charge of Domestic Battery, where the suspect is said to have thrown the accuser to the ground and kicked them in the stomach.
The bond amount in the April incident is reported to have been $1,500.
The newly amended affidavit also releases details about a 911 call, made by the victim on August 27. Sheriff’s officials describe the call as “frantic” and say that both the victim and a voice similar to Drengenberg can be heard in the phone call recording. During the call the assailant was identified by the victim as Drengenberg, and the male voice is quoted as saying, at one point, “you called the police? You’re [expletive deleted] going to need them now, [expletive deleted].”
Following the August 27 incident, the accuser was said to have been suffering from a broken rib, a partial deflation of their lung, a swollen eye, multiple scrape marks, and other facial trauma. The victim was also reported to have a “tremendous amount of cactus” stuck in their legs. Deputies say that it took medical personnel approximately 30 minutes to remove the cactus.
Drengenberg is awaiting a Preliminary Hearing in Circuit Court to determine if the case will be bound over to District Court.
He is currently in custody on a reported $50,000 cash-only bond. He is also reportedly being held on a recommended bond revocation for the April 2019 incident.
All of those cited or arrested are presumed innocent until convicted in a court of law. Charges are subject to change following official filings from the Natrona County District Attorney’s Office.
