Expanded charges for Kaminski — Officer faces multiple felony charges

A former Newcastle police officer has been charged with multiple felony and misdemeanor offenses following an investigation by the Wyoming Division of Criminal Investigation into allegations of domestic violence involving a former girlfriend. The same officer was arrested and originally charged in May, prior to the DCI Investigation. 

According to an amended misdemeanor and felony information filed June 12 in Weston County Circuit Court, Nicholas Joseph Kaminski faces six criminal counts stemming from three separate incidents alleged to have occurred between July 2025 and May 2026. 

The charges include two felony counts of aggravated assault and battery and one felony count of felonious restraint, along with three misdemeanor counts of domestic battery.

Court records show Kaminski waived his right to a preliminary hearing on June 12. A district court initial appearance on the amended charges has been scheduled for June 23 at 3:30 p.m. in Weston County District Court.

Unlike documents filed in connection with the original charges, the amended court filings identify the alleged victim only by initials and contain redactions intended to protect her identity.

The felony aggravated assault and battery charge alleges that on or about May 15, 2026, Kaminski threatened the victim with a drawn deadly weapon. The charge carries a maximum penalty of 10 years’ imprisonment, a $10,000 fine or both.

A second felony aggravated assault and battery charge alleges Kaminski threatened the same woman with a drawn deadly weapon during a Dec. 10, 2025, incident. That charge carries the same potential penalty.

Kaminski is also charged with felonious restraint related to the Dec. 10 incident. Prosecutors allege he knowingly restrained the victim under circumstances exposing her to a risk of serious bodily injury. The offense is punishable by up to five years’ imprisonment and a $10,000 fine.

The three misdemeanor domestic battery charges allege Kaminski unlawfully caused bodily injury to the victim during separate incidents on July 29, 2025, and Dec. 10 and May 10, 2026. 

According to an affidavit of probable cause filed by DCI Special Agent Ed Rosier, the investigation began after allegations were reported in May 2026. The affidavit states investigators interviewed the alleged victim and reviewed photographs documenting injuries, police reports, radio logs and surveillance video.

The affidavit states that the July 2025 incident occurred after an argument in Newcastle. Investigators allege Kaminski removed the woman from a vehicle, pushed her to the ground and caused bruising and other injuries.

Court records further allege that during the Dec. 10, 2025, incident, Kaminski prevented the woman from leaving an encounter, forcibly removed her from a vehicle and displayed a knife. The affidavit states the woman told investigators she feared being killed during the incident.

A third confrontation is alleged to have occurred May 10, 2026, at Weston County Health Services. According to the affidavit, the woman reported Kaminski confronted her while she was working at the hospital and physically grabbed her, causing injuries that were later documented by law enforcement.

Investigators also reviewed damage to a Newcastle Police Department patrol vehicle that occurred on Dec. 10, 2025. The affidavit states DCI reviewed surveillance footage, police reports and radio logs while examining that portion of the investigation.

The criminal charges remain allegations. Kaminski is presumed innocent unless and until proven guilty in court.

Court records indicate the case is being prosecuted by DaNece Day, who was appointed as special prosecutor for Weston County. The probable cause affidavit was prepared by DCI.

Kaminski’s June 23 district court appearance is scheduled to occur at the same time as the hearing originally set as a preliminary examination, according to court records.

As previously reported by the News Letter Journal, Kaminski was first charged in May with felony aggravated assault and battery after investigators alleged that he pointed a handgun at the victim during a domestic dispute at his Moore Lane residence on May 15.

According to court documents filed at that time, the victim told investigators Kaminski asked her to come to his residence because he believed he was going to lose his job. She reported that Kaminski believed she had informed others about video footage from Weston County Health Services depicting a physical altercation between the pair on May 10.

The victim told investigators that once she arrived, Kaminski became angry and accused her of being responsible for jeopardizing his law enforcement career. According to the affidavit, Kaminski then drew what she described as a black 9 mm handgun and pointed it directly at her while demanding information.

Court documents state the victim reported that Kaminski threatened to kill her during the encounter and that she eventually provided false information in an effort to calm him and leave safely.

The aggravated assault charge was filed May 26. Days prior to the filing, Kaminski was first arrested for stalking on May 24 after an incident that began on May 23.

According to court records, Newcastle police officers conducting a DUI investigation at Weston County Health Services learned that Kaminski was allegedly repeatedly calling and texting the victim while she was at work.

Investigators reported that Kaminski sent numerous messages demanding that she come outside or answer her phone. Court documents state the victim repeatedly asked him to stop contacting her and leave her alone.

The affidavit further states that Kaminski later appeared near the hospital, approached the victim’s vehicle and drove through hospital parking lots at a high rate of speed.

During a subsequent traffic stop, officers reported finding a loaded Glock 48 handgun in Kaminski’s waistband, along with a folding knife and brass knuckles.

The stalking allegation remains separate from the felony assault charges.
