Dubuque Brother and Sister Responsible for Selling Hundreds of Pounds of Methamphetamine Plead Guilty to Conspiring to Distribute Methamphetamine

A brother and sister who conspired to distribute methamphetamine within 1,000 feet of a protected location pled guilty today in federal court in Cedar Rapids.

Jacob Patrick Demaio, age 42, and Codi Lyn Demaio, age 35, both from Dubuque, Iowa, were each convicted of one count of conspiring to distribute at least 500 grams of a mixture or substance containing a detectable amount of methamphetamine, and at least 50 grams of actual (pure) methamphetamine, within 1,000 feet of a protected location.

Evidence at a prior hearing showed that Jacob Demaio sold hundreds of pounds of methamphetamine to multiple people between 2019 and 2022.  He arranged for drug transactions to occur at stash houses located in Dubuque within 1,000 feet of schools and playgrounds.  Drug customers dropped off hundreds of thousands of dollars at those stash houses; that money was intended for Jacob Demaio. 

At a prior hearing, evidence showed that Codi Demaio also sold pounds of methamphetamine to several people in Dubuque between 2019 and 2022.  On two occasions when her brother was incarcerated, she took over his drug operation and sold tens of pounds of methamphetamine.  She was once instructed to go to California with $25,000 to buy drugs, though she instead traveled to Las Vegas and lost all of the money.  

At plea hearings, Jacob and Codi Demaio admitted that they conspired to distribute at least 500 grams of a mixture or substance containing a detectable amount of methamphetamine, and at least 50 grams or more of actual (pure) methamphetamine, within 1,000 feet of a protected location.   

Sentencing before United States District Court Judge C.J. Williams will be set after a presentence report is prepared.  Jacob and Codi Demaio remain in custody of the United States Marshal pending sentencing. 

For conspiring to distribute methamphetamine within 1,000 feet of a protected location, both Jacob and Codi Demaio face a mandatory minimum sentence of 10 years’ imprisonment and the following maximum penalties: not more than life imprisonment without the possibility of parole; a fine of not more than $20,000,000; a mandatory special assessment of $100; and a term of supervised release of at least 10 years and up to life. 

The case is being prosecuted by Special Assistant United States Attorney Devra Hake.  It was investigated as part of the Organized Crime Drug Enforcement Task Force (OCDETF) program of the United States Department of Justice through a cooperative effort of the Dubuque Drug Task Force, Dubuque County Sheriff’s Office, Dubuque Police Department, Quad City Metropolitan Enforcement Group, Federal Bureau of Investigation, Drug Enforcement Administration, United States Postal Inspection Service, and the Iowa Division of Criminal Investigation Criminalistics Laboratory.
