Botio Tachkov, a renowned economist, who was brutally attacked by a large pack of stray dogs in the Malinova Dolina quarter in the Bulgarian capital at the end of last month, has passed away.

Tachkov died early Sunday morning at the Military Medical Hospital in Sofia, the largest private TV channel bTV informs, citing his family. The cause of death has been listed as multiple organ failure. He had serious cardiac problems during the entire hospital stay, despite the fact that his wounds had been heeling well.

Tachkov, 88, is one of the most prominent Bulgarians in the US. He was born in the western city of Pernik and was a graduate of the Sofia University with a Major in Economy. He immigrated to America in 1962.

There, he became an associate professor at the Columbia University in New York and PhD later. The year 1968 marked the start of his Wall Street career, where he rose to President of an investment bank. He had worked for the US State Department, the UN, as economic advisor for the government of Indonesia, and had lectured at many universities in the US and Germany.

The Professor, who returned to Bulgaria wishing for a quiet retirement, was fluent in six languages, and had four published books.

The accident triggered public outrage, as the city has been struggling to cope with its increasing stray dog population for years now.
