One of the suspects charged in connection with the kidnapping and murder of Danville resident Greg Davis four years ago is the wealthy founder of a Los Angeles medical research company. Serhat Gumrukcu, (Gum Ru Ku) 39, co-founded Enochian (Eh-NO-Kian) BioSciences Inc. Enochian Chief Executive Mark Dybul said Gumrukcu has had no formal role in the company, and that his role as a scientific adviser has ended. According to the report, Gumrukcu is the company’s largest shareholder and that last week he sold about 253,000 shares at a price of $8 each, grossing over $2 million dollars. Gumrukcu was arrested this week along with another suspect identified as Las Vegas, Nev. resident Berk Eratay, 35. Both were arrested this week on a federal warrant alleging that they “knowingly and intentionally conspired to use interstate commerce to facilitate a murder-for-hire. Two other suspects have also been arrested in the case including the alleged kidnapper, Jerry Banks, 34, of Fort Garland, Colorado. The FBI says Jerry Banks posed as a federal agent to kidnap Davis from his home in Danville on Jan. 6, 2018. Davis was found the next day hand-cuffed and dead from multiple gunshot wounds on Peacham Road in Barnet. Banks has been accused by the government of kidnapping Davis from his home and then killing him. Also charged in connection with the case was Aron Lee Ethridge, 41, of Henderson, Nev., who has also been indicted on a felony kidnapping charge in connection with the murder of Davis. Ethridge is alleged to have communicated with Banks before and after the kidnapping and murder.
