Professor Ramazan Gençay, who has been missing in Colombia since Dec. 6, has been found killed, his wife announced late Thursday.

The cause of death has reportedly been stated as poisoning.

According to a security official of Medellin, a city in the south American country where the professor went missing, Gençay was poisoned by a group of women.

Underlining that his death is not officially registered yet due to the necessity of a DNA test, police chief Andres Tobon said that the investigation is still ongoing.

Gençay, a professor of economics at Simon Fraser University in Canada where he settled in the early 1990s, was in Colombia's second-largest city Medellin for a seminar at EAFIT University on Nov. 28. He decided to prolong his stay in the city, where he had been to before. Gençay was last seen with unidentified people at a salsa club on Dec. 6, and an investigation showed money was withdrawn from his credit cards on Dec. 7 and Dec. 8.

His family said on social media that Gençay was an experienced traveler who enjoyed hiking as well as salsa dancing. The professor worked as a guest lecturer at EAFIT University in 2016 according to his CV. He also served as a guest lecturer in Universidad del Rosario in Bogota, Colombia in 2015. The family said Colombian authorities in cooperation with Canadian security officials were investigating Gençay's disappearance.
