Speaking of the Shelby Houlihan case, here's another athlete that was found to be lying about doping. Her husband was extradited last year.
"It has now been a good four years since Lisa Nemec tested positive for EPO during a training check after her seventh place at the Berlin Marathon 2015 and was given a four-year doping ban. At the Berlin Marathon itself, she had delivered a negative test. A detailed report in the Neue Zürcher Zeitung (NZZ) on Sunday presents new interesting details about the career of the Croatian national record holder, who was born in the USA, won the Linz Marathon in 2011 and achieved her personal best of 2:25:44 hours in Zurich in 2013 ran.
The 35-year-old is said to be a customer of Dr. Mark Schmidt, whose doping network was uncovered by the raid and both preparatory and subsequent investigations at the Nordic World Ski Championships in Seefeld in February 2019. According to the NZZ, the German is said to have betrayed Nemec during interrogation. It is also interesting that the Swiss medium tells of a friendly relationship with Walter Mayer, the Austrian cross-country ski trainer with a considerably more frequent direct proximity to doping affairs. Investigations are currently underway against Mayer; he and Nemec’s husband may have significantly supported the athlete in cheating.
Lisa Nemec herself, who reached her sporting climax with fourth place at the 2014 European Championships in Zurich, has always protested her innocence and sees herself as the victim of an intrigue. In her career she achieved remarkable results in World Marathon Majors in Berlin, Boston and New York. In 2015, shortly before her doping ban, she won the Wörthersee Half Marathon, where she landed on the podium in 2010 and 2012."
