A man faces up to 190 years in prison for fentanyl distribution leading to the death of at least one other person in Boulder County.

Carlos Centeno-Izaguirre pleaded guilty to several counts, including distribution of a controlled substance resulting in death as well as distributing both fentanyl and heroin, according to a news release from the 20th Judicial District Attorney’s Office. Depending on if a judge determines that the counts run concurrent or consecutive, Centeno-Izaguirre faces from 12 to 190 years in prison.

Investigators have connected Centeno-Izaguirre to at least one fentanyl-related overdose in Boulder County, according to the release. Police found Boulder man Tyson Baker dead in his home in September 2023. They later determined that the fentanyl pill that killed him had been sold by Centeno-Izaguirre.

“This guilty plea to all charges is a direct result of the outstanding teamwork that went into the investigation and prosecution,” said 20th Judicial District Attorney Michael Dougherty in the release. “It is the best possible outcome in a tragic case such as this one.”

Authorities had already been investigating Centeno-Izaguirre at the time of Baker’s death, and had coordinated several purchases of fentanyl from the dealer, according to the release. After Baker’s death, authorities executed a search warrant on the defendant’s home and seized fentanyl pills, heroin and cocaine.

Centeno-Izaguirre’s sentencing is scheduled for Dec. 10.
