After being fired in late 2017, Matraimov became a central figure in an ongoing large scale money-laundering case, one of the biggest scandals in the history of Kyrgyz politics.
[citation needed] His longest managing position tenure lasted for six years: from 2007 till 2013 Matraimov was head of Osh department of the State Customs Service.
[6] After Atambayev stepped down as the president in December 2017, Matraimov filed a lawsuit against the state, and in 2018 the court made a decision to reinstate him as the deputy head of the Customs Service.
[10] In the investigation, Radio Liberty journalists claimed that Matraimov earned his wealth while being part of a corruption scheme that allowed a group of Chinese companies led by the secretive Abdukadyr family bring goods into Kyrgyzstan without paying any customs fees.
[10] One of the major sources of the investigation, a self-confessed money launderer Aierken Saimaiti who worked for Abdukadyrs, was murdered in Istanbul in November 2019.
Kyrgyz National Security Committee (GKNB) claimed that Matraimov was alleged to have made hundreds of millions of dollars from smuggling.
After analyzing Turgunova's private social media accounts, Kyrgyz journalists revealed she owned expensive watches and jewelry that she would not be able to afford with her official salary.
[23] In 2020 Bellingcat and the OCCRP connected Matraimov and Turgunova to properties, including a cottage at Issyk-Kul[24] and a luxury apartment in Dubai.
