Another man who allegedly participated with others in a firearms burglary in early April has been arrested and pleaded not guilty Thursday in Mower County Court.

Shane Douglas Postema, 22, of Tahlequa, Okla., pleaded not guilty to three felonies: first-degree burglary of dangerous weapons, second-degree burglary and theft.

According to the court complaint, Postema allegedly attempted to break into an Austin home and steal a safe that contained guns and knives with another man, Jayson Pomsyda, 18, of Austin. Pomsyda was charged on April 12 with the same crimes. The maximum penalty for firearm theft is 20 years in prison and a $100,000 fine.

According to the complaint, the owner of the northwest Austin home was on vacation when a woman watching his home called him and said it appeared as if someone tried to break in. The homeowner told the woman to check his safe, which appeared to be undisturbed, along with the rest of the house, the report states. Officers then responded to the home in the 900 block of Fifth Avenue NW on April 5 after the woman watching it reported that someone broke into the house, stole the safe and left a mess.

According to the complaint, the safe had several thousand dollars worth of merchandise, including multiple rifles, a shotgun, about 25 knives, a pistol, valuable coins, birth certificates and baby books.

Authorities later spoke with a man who found two of the rifles in the 900 block of Fourth Avenue NW and inferred who the suspects may be, according to the complaint. Authorities learned about Pomsyda, found him on April 10 at the 600 block of Ninth Street NW and arrested him.

Pomsyda allegedly told authorities that he was with two teens, who went to the home several times. Police interviewed both teens allegedly involved in the case, and both said they broke in through a window and discovered that Pomsyda and Postema were already inside, trying to break into a safe. The court complaint adds that the teens left with a smaller safe.

Pomsyda admitted to breaking into the safe with Postema and stashing the guns in a nearby wooded area, according to the complaint. Pomsyda then allegedly showed authorities where the guns were.

Pomsyda was recently convicted of fifth-degree assault and sentenced to one year of probation and fined $300. A review of Postema’s criminal record shows convictions in four other states, the complaint adds, among several failure to appear in court charges.

Postema’s pretrial is set for June 8.
