Terry Lee Christian on Wednesday was sentenced to 15 years in federal prison for selling a lethal combination of drugs that resulted in the death of Socrates S. Kokkalis, the son of Greek billionaire businessman, Sokratis P. Kokkalis. Christian, 36, pleaded guilty in October 2019 to charges related to selling the drugs that killed 34-year-old Sokratis S. Kokkalis in July 2018. According to authorities, Christian sold cocaine laced with heroin and fentanyl to Kokkalis outside Jack Cleveland Casino. Sokratis S. Kokkalis Cleveland Police Department found the Greek billionaire's son dead in his Cleveland hotel room and later discovered a bag of suspected cocaine. “This case is yet another reminder that any drug people are buying likely contains fentanyl, which can kill even in very small doses,” U.S. Attorney Justin Herdman said. “By all accounts, the victim in this case believed he was buying cocaine, not opioids," he added. Socrates P. Kokkalis, is the founder of a Greek telecommunications company and chairman of the Greek soccer team Olympiacos F.C. His son was the team's vice-president.
