A man who was wearing demonic, white-faced makeup when he fatally slashed a 29-year-old homeless man to death armed with a knife has been convicted of murder.

A jury found Christian Gulzow, 37, who was originally charged with first-degree murder, guilty of second-degree murder following a four-day trial.

Gulzow, who identified as Christöf Gülzowprüzenstein, faces a possible sentence of up to 48 years in prison, according to Ken Lane, spokesman for Denver District Attorney Beth McCann.

Gulzow fatally stabbed Brian Lucero in the early morning of May 23, 2017, in the parking lot of Torchy’s Tacos at 11th Avenue and Broadway, following a confrontation between the two. Lucero suffered a stab wound to the neck.

Friends and family have said Gulzow was a lonely, troubled man who endlessly shared his dark observations and videos in social media posts. He often circulated around downtown Denver on his scooter wearing elaborate demon, vampire and ghoul role-playing costumes.

Gulzow told police the homeless man threatened him and yelled at him “to get out of my alley,” according to an arrest warrant affidavit. He claimed the victim attacked him and stole his scooter, but witnesses said Gulzow was the aggressor.

Gulzow, who worked at a pizza restaurant, has a son and lived with his mother. He was the vocalist of a heavy metal band. Gulzow claimed to be the owner, founder, producer and promoter of @ΨWorldMusicStudiosΨ and the goth-metal band, The Paranormals, which in October released the album, “The Dark Saints Kings,” with original songs that included “Rulers of Darkness,” “Sinful Flesh,” and “Tortered (sic) Souls.”

The fakes will be “exposed and disposed of: Behold I am The True Saten (sic),” Gulzow wrote in a March 2017 Facebook post. Gulzow posted Nazi propaganda posters and pictures of himself in elaborate costumes, including the Joker supervillain from the Batman comic books.

His posts offered dark witticisms: “I like sudden death moments when you almost just died and made it out alive.” On the topic of shocking himself with a Taser he wrote: “If I had one I might kill myself with it (be)cause it’s a rush.”
