U.S. authorities provided Mazeika’s credit card activity, which showed him using a card in his own name at Newark Airport on Nov. 24 and Düsseldorf Airport on Nov. 25, as well as at Vnukovo International Airport in Moscow on Nov. 28 and Connecticut on Nov. 29, 2019.
Johnson was paid $10,000 by Fecker’s wife—but in euros, which he had to convert into dollars, creating a paper trail. Mazeika apparently wasn’t paid promptly and texted Fecker to ask for his payment, which Fecker responded he would wire, leaving more evidence.
The FBI also shared with Dutch and German police that Causey, who had been arrested in Colorado on drug and firearms charges, volunteered that he’d been doing protection work for Lukas Fecker, and that his bank records showed payments in December 2019 from Credit Suisse Bank on behalf of Fecker’s company, Innovation Brain. Causey even texted his girlfriend bragging about what he was earning: “$230,000 in 2 months,” he texted. “The work, though…Lord.”
“That’s a lot!” she responded. “As long as you’re OK, I’m OK.”
“I’m good,” Causey texted back. “It’s just a job.”
Thanks to their investigative work, Dutch and German police had their guys nailed—but other than Fecker, who was quickly arrested, the suspects were all long gone back to the United States.
On Feb. 20, 2020, the Public Prosecutor of the Judicial District of Maastricht, Netherlands, issued arrest warrants for Causey, Mazeika and Johnson on 19 charges including murder, aggravated manslaughter and extortion resulting in death. In accordance with an extradition treaty, U.S. authorities moved quietly, deeming all three men flight risks if they discovered the warrants for their arrest. In a coordinated effort in April, authorities simultaneously arrested Causey in Colorado, Johnson in Mississippi and Mazeika in Connecticut.
