Spencer man gets 19-year federal prison sentence for shooting, meth convictions

A Spencer man who sold meth for over a year and shot at a drug buyer’s home last year was sentenced June 28 to 19 years in federal prison for meth distribution and gun charges.

The U.S. District Attorney’s Office reported Travis Wayne Mattson, 35, received the sentence in U.S. District Court in Sioux City.

Mattson pleaded guilty to conspiracy to distribute methamphetamine and possession of a firearm in furtherance of a drug trafficking crime on November 26, 2018.


Mattson was arrested on May 11, 2018, following a Clay County Sheriff’s Office investigation into a drive-by shooting at Country Villa Trailer Court, 3655 240th Avenue in Clay County.

The sheriff’s office determined a home was struck multiple times by someone shooting from a vehicle from the road next to the trailer court.

The investigation, which also involved the Iowa Department of Safety Division of Narcotics Enforcement and the Spencer Police Department, resulted in a search of Mattson’s residence in Spencer.


Authorities found meth, drug paraphernalia, a digital scale, 9mm rounds of ammunition, a bulletproof vest and two guns.

He was arrested and the U.S. Attorney’s Office in Sioux City led the prosecution.

At Mattson’s plea hearing in November, he admitted he was involved in distributing nearly 10 pounds of meth mixture in the Spencer area from January 2017 to May 2018, according to the US Attorney’s Office.

Mattson reportedly kept the meth and drug proceeds in safes inside his home.


The U.S. Attorney’s Office indicated evidence showed Mattson was responsible for shooting at the trailer court residence, which the office added was the home of a drug customer.

Additional evidence showed Mattson had installed metal and wood barricades to fortify his home. He also installed security cameras to monitor entrances to the residence.

U.S. District Court Chief Judge Leonard T. Strand sentenced Mattson to 228 months in federal prison. Mattson must also serve a four-year term of supervised release following the prison term.

Mattson will not be eligible for parole, as there is no parole in the federal system.

He is in U.S. Marshal custody until he is transported to a federal prison.


Assistant U.S. Attorney Mikala Steenholdt prosecuted the case. It was investigated by the Iowa Division of Narcotics Enforcement; Iowa Department of Criminalistics Investigation; Spencer Police Department; Clay County Sheriff’s Office; Iowa Great Lakes Drug Task Force; Bureau of Alcohol, Tobacco, Firearms and Explosives; HEAT Team and the Clay County Attorney’s Office.
