EVANSVILLE — Isaac J. Horne, described by federal prosecutors as the primary source of supply for a methamphetamine ring that operated across Vanderburgh County, was sentenced this month to 15 years in federal prison.
U.S. District Judge Richard L. Young imposed the sentence July 22, according to court records. Horne, 47, had pleaded guilty in May to a conspiracy count, among other charges, just two days before his trial was set to begin.
His co-defendant, Christopher M. Youngblood, 42, was sentenced May 18 to seven years after pleading guilty to one count of conspiracy to distribute methamphetamine. Both men will also serve five years of supervised release, records show.
Methamphetamine, a potent stimulant, may have become overshadowed in recent years by the deadly rise of fentanyl, but the drug continues to show up in the toxicology results of the city’s overdose victims, data maintained by the Vanderburgh County Coroner’s Office shows. According to prosecutors, Horne led a ring that supplied about 16 pounds of meth to the Evansville area within just a seven-month span in 2024 by supplying other distributors, including Youngblood, who in turn sold to lower-level street dealers and, ultimately, users.
Tom Wheeler, U.S. attorney for the Southern District of Indiana, said in the release that the methamphetamine amounted to “thousands of individual doses introduced into our community.”
The case also highlights shifting priorities and programs under the Trump administration as leadership works to reshape federal law enforcement from top to bottom, instituting a barrage of policy and cultural changes and aggressive public information campaigns.
The U.S. Attorney’s Office for the Southern District of Indiana announced both sentences Monday by crediting the investigation to a multiagency initiative stemming from one of the first executive orders President Donald Trump issued upon his return to the White House in January 2025: “Protecting the American People Against Invasion.” The order directed the Department of Justice to create a sprawling network of regional federal, state and local law enforcement partnerships, among other directives.
In the news release announcing Horne’s and Youngblood’s sentences, the office said the region’s task force created under that order — known as the Crossroads Homeland Security Task Force, or HSTF — “led the investigation,” even though the FBI and Homeland Security Investigations jointly announced the creation of the task force in November 2025 — eight months after prosecutors first charged Horne, and despite the fact the U.S. Drug Enforcement Administration played a leading role in the case going back to at least 2024, court records show.
Kelsie Clayton, a spokeswoman for the U.S. Attorney’s Office for the Southern District of Indiana, said any apparent mismatch in timing as to who led the investigation had more to do with ever-changing federal nomenclature than anything else, describing the Crossroads HSTF as an evolution of the Southern District’s long-running participation in Project Safe Neighborhoods. She couldn’t say precisely when the new Crossroads task force became operational.
“When Trump took office, I think we’re all familiar; he likes to kind of redo everything and put his own name and spin on stuff, so it’s essentially it’s just PSN,” Clayton said, referring to Project Safe Neighborhoods. “He put the new name as ‘Operation Take Back America’ … Then a few months after that, they announced this Homeland Security Task Force Situation.”
But the case against Horne began earlier, and closer to home.
A $700 buy on Covert Avenue
On the afternoon of Aug. 26, 2024, a confidential informant working with the Evansville-Vanderburgh County Drug Task Force was searched, fitted with recording equipment and handed $700 in marked bills, according to an affidavit sworn by a sheriff’s deputy assigned since 2015 to the DEA as a federal task force officer.
The informant texted Horne to arrange a meeting. Horne was ready, the affidavit says — but the sale had to wait. The owner of the house where the methamphetamine was stored had not yet gotten home from work.
Investigators followed their man on the inside to a house on Covert Avenue and watched from outside. Twenty-five minutes later, they returned with a plastic bag of crystalline powder. A DEA laboratory in Chicago later measured it at 117.8 grams of pure methamphetamine — more than twice the quantity that triggers a 10-year mandatory minimum sentence under federal law.
Horne left the house on foot a short time later, checking the area and looking inside parked cars in what the officer described as an apparent effort to spot surveillance. A drone recorded him.
The transaction itself was never captured on video. The source’s camera failed, the affidavit says, leaving investigators with audio alone. They identified Horne by his voice, which they said they recognized from calls he had made while held at the Vanderburgh County jail.
The phone
In the months that followed, investigators subpoenaed records for the number the informant had used to communicate with the Covert Avenue dealer and obtained state court authorization to track the device, according to the affidavit. The account came back in Horne’s own name.
That September, Horne was arrested on an unrelated domestic battery charge — and the phone went to jail with him. Location data tracked it from his home to the Vanderburgh County jail, where it remained for the length of his stay. Jail records confirmed he had a cellphone when he was booked, and 24 minutes after his release the next morning, the phone began moving again.
Investigators were convinced they had their man.
From state court to federal
Horne was arrested on state methamphetamine charges in February 2025. Federal prosecutors filed their criminal complaint 26 days later — a common occurrence in narcotics cases involving large quantities of seized drugs, money or illegal firearms.
Youngblood, who is not named anywhere in the initial complaint against Horne, entered the case as a co-defendant in April 2025 when a grand jury returned an indictment charging both men. The complaint makes no mention of the Crossroads Homeland Security Task Force. It names the DEA, the local drug task force, the sheriff’s office and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.
On Dec. 15, 2025, Horne rejected a plea offer in open court. Three days later, a grand jury returned a superseding indictment that added a conspiracy charge against Youngblood — who accepted a plea agreement of his own that same day.
Horne kept pressing toward trial. In January, he refused to waive a formal reading of the new indictment, requiring a prosecutor to read it aloud in court. In April, less than two weeks before jury selection was to begin, a grand jury returned a second superseding indictment naming him alone. He pleaded guilty May 4.
What Horne and Youngblood pleaded guilty to
Horne pleaded guilty May 4 to all three counts he faced under the second superseding indictment — conspiracy to distribute methamphetamine and two counts of distribution — and Young sentenced him to 180 months on each, to be served concurrently. His judgment lists no dismissed counts. Earlier indictments were dropped as each was superseded, court records show.
Youngblood’s case played out differently. He pleaded guilty in March under a written plea agreement to a single conspiracy count, and prosecutors dismissed the remaining charges against him — one of them orally, at his sentencing hearing. Young sentenced him to 84 months and recommended he be evaluated for residential drug treatment and mental health care in prison.
Horne contested the presentence investigation report prepared in his case, filing an objection in June with a laboratory report attached. Prosecutors answered with two DEA chemical analysis reports of their own. The dispute was argued behind closed doors: at the government’s request and without objection from Horne’s attorney, Young sealed the courtroom and then reopened it to impose the sentence.
Court records show Horne’s federal term will run consecutively to any sentence imposed in a pending case against him in Henderson County District Court in Kentucky.
