Missouri House candidate charged in plot to plant drugs on Republican primary opponent

The Missouri House of Representatives on Feb. 19, 2026 (Tim Bommel/Missouri House Communications). A Republican legislative candidate in Joplin plotted to plant cocaine and Adderall on his primary opponent in an effort to derail her campaign, federal prosecutors allege.

Thomas Ross, who won the Republican nomination for Missouri’s 161st House District by only 32 votes, was charged Wednesday with conspiracy to distribute a controlled substance.

A criminal complaint filed Wednesday in U.S. District Court for the Western District of Missouri alleges Ross spent weeks discussing a plan to plant the drugs on Louise Secker, his opponent in the Aug. 4 Republican primary.

Ross’ former campaign manager reported the alleged plot to the Joplin Police Department on July 30, according to a probable cause statement by FBI Special Agent Brandon Bernhardt.

The former campaign manager provided Joplin police with a nylon glove containing a plastic bag of white powder that tested positive for cocaine and a pink and white pill identified as Adderall, Bernhardt wrote.

Screenshots of text messages reviewed by Bernhardt suggest Ross and the former campaign manager discussed the plot as early as May 31 and show them referring to it in coded language as the “substance of the matter” or the “substance of it all,” according to the probable cause statement.

The former campaign manager said Ross asked him to plant the drugs in Secker’s purse or vehicle while Ross was on vacation in Myrtle Beach, South Carolina, Bernhardt wrote.

Ross sent the campaign manager a text message on June 15 saying: “Hope you all are having success knocking doors and getting the substance of the matter sorted this week.”

Court documents quote a June 18 message from Ross that read: “Any luck with the substance of the matter? I wont be gone much longer.”

During a July 31 meeting at Ross’ house, the former campaign manager used a covert device provided by the FBI to record Ross. He told Ross he still had “the bag and addies” and asked Ross if he still wanted him to “try,” suggesting they could call in an anonymous tip about drugs in Secker’s car.

According to court documents, Ross replied, “If you can pull it off…pull it off.”

In a press release from the U.S. Department of Justice Thursday, Matthew Price, U.S. attorney for the Western District of Missouri, said “the American people deserve confidence in an electoral process that has served our nation for generations.”

“Candidates are expected to conduct their campaigns with integrity, honesty and respect for their opponents,” he said, “allowing voters to make informed decisions without fear of misinformation or undue influence.”

Chris Ornerod, special agent in charge in the FBI Kansas City field office, described the allegations as “substantial and serious.”

“As this case moves through the judicial process,” Ornerod said, “it’s important that it proceeds fairly, impartially and in accordance with the rule of law.”
