CEDAR RAPIDS — A Marshalltown man who illegally possessed nearly three kilograms of methamphetamine was sentenced Wednesday to more than 12 years in federal prison.

Marcos Servin, 23, received the prison term after a Sept. 3, 2025, guilty plea to possession of a controlled substance with the intent to distribute.

Evidence at the sentencing hearing showed that law enforcement officers stopped Servin as he was driving on Oct. 23, 2024. During the traffic stop, a narcotic detection K9 positively indicated the presence of an odor of a controlled substance within Servin’s car. Officers searched Servin’s car and located over 900 grams of ice methamphetamine. Law enforcement officers later searched a Des Moines home that Servin had left earlier that day. Officers located over 1,900 grams of ice methamphetamine inside the home.

Servin was sentenced in Cedar Rapids by United States District Court Chief Judge C.J. Williams. Servin was sentenced to 151 months of imprisonment. He must also serve a five-year term of supervised release after the prison term. There is no parole in the federal system.

Servin is being held in the United States Marshal’s custody until he can be transported to a federal prison.

The case was prosecuted by Special Assistant United States Attorney Michael Hudson and investigated by the Federal Bureau of Investigation, the Iowa Division of Narcotics Enforcement, the Mid-Iowa Drug Task Force, the Iowa State Patrol, and the Tri-County Drug Enforcement Task Force, consisting of the Waterloo Police Department, Cedar Falls Police Department, Black Hawk County Sheriff’s Department, Evansdale Police Department, Waverly Police Department, Hudson Police Department, La Porte City Police Department, and the Bremer County Sheriff’s Office.
