BAY CITY, MI — A woman has received federal prison time for illegally buying a gun for her boyfriend, who later used it to kill his younger brother in Saginaw Township.

U.S. District Judge Thomas L. Ludington on Friday, Jan. 10, sentenced Jessica M. Peek, 25, to eight months in a federal prison. The judge allowed Peek until March 31 to surrender to authorities and begin serving her sentence.

Once Peek serves her term, she’ll be on supervised release for an additional three years, Ludington ordered.

Peek in June pleaded guilty to one count of sale or transfer of a firearm to a prohibited person, a 10-year felony.

The charge stems from Peek having bought a Kahr .45-caliber semiautomatic pistol from Showtime Guns & Ammo, 3621 Bay Road in Saginaw in August 2017. She bought it for her then-boyfriend, Adrian L. Villanueva, knowing he had been convicted of a felony and thus banned from possessing a gun, prosecutors alleged.

Villanueva had picked out the gun he wanted, provided Peek with the money to purchase it, and accompanied her to the business, prosecutors said. When she bought the gun, Peek misrepresented that she was buying it for herself, prosecutors alleged.

Villanueva kept the gun after the couple broke up, prosecutors alleged.

Villanueva on the afternoon of March 4, 2019, repeatedly shot his 25-year-old brother, Jonathan I. Villanueva, inside their shared residence at 4035 Emerick St. in Saginaw Township. Adrian Villanueva called 911 to report the shooting.

Multiple relatives were present in the house, including the defendant’s two young children, prosecutors have said.

Police from multiple agencies responded to the scene and engaged Villanueva in a four-hour standoff. During the negotiations, Villanueva eventually let some of his family members leave the house uninjured and ultimately surrendered to police.

Saginaw County Emergency Services Team members then entered the house and discovered Jonathan Villanueva’s body.

The Villanueva brothers were natives of Georgia, according to their sister, Erica Durham, of Alabama. She previously said they were very close and that Adrian Villanueva has suffered from mental health issues much of his life.

Adrian Villanueva in October pleaded no contest to second-degree murder, five counts of felony firearm, two counts of unlawful imprisonment, and two counts of felonious assault. In exchange, the prosecution agreed to dismiss a charge of open murder, which contains both first- and second-degree murder.

Saginaw County Circuit Judge Janet M. Boes on Dec. 3 sentenced the 34-year-old Adrian Villanueva to 48 years to 75 years in prison.
