BOSTON (WHDH) -- A self-described Satan worshipper from New York was held on $100,000 bail after pleading not guilty after allegedly threatening to kill a yoga and fitness instructor he met at a bar in Boston’s Faneuil Hall.

Police said 21-year-old Christopher Cori of Queens, N.Y. met a young woman at Mija, a popular Mexican restaurant, on Jan. 19. Cori got her number and then repeatedly threatened her life, according to the report.

According to the police report, the victim gave Cori her business card because he said he was interested in fitness. He then gave her a pocket watch. The woman told prosecutors he behaved bizarrely at the bar, even playing with a knife.

The 25-year-old victim, who teaches yoga at a gym in Allston, left with her friends, but police said Cori texted her death threats.

One threat said, “How would you like to find out what it’s like to be burned alive?” Another threat said, “You are nailing shut your own coffin darling” and “I will burn your house down and kill you without blinking an eye.”

Police said when they caught up with Cori he had handcuffs and a satanic book called “Lucifer Principles.” When Cori was held overnight in a Brighton jail he allegedly etched a pentagram into the glass.

7News reached out to the victim, but she did not want to comment at this time.

Cori was charged with making threats to kill, criminal harassment, making annoying and harassing phone calls and willful and malicious destruction of property. He was held on $100,000 bail and will undergo a mental health evaluation at Bridgewater State Hospital.
