Christian Gulzow, 37, was sentenced in Denver District Court on a second-degree murder conviction. He was found guilty by a jury in June.
Gulzow was wearing white clown makeup with black streaks and a glove with 2- to 3-inch blades on each finger, witnesses said.
Gulzow was the vocalist of a heavy metal band and claimed to be the founder and promoter of @ΨWorldMusicStudiosΨ and the goth-metal band The Paranormal, the Denver Post reported. He worked at a pizza restaurant and had a son. His Instagram account contained multiple photos of him wearing white makeup. Witnesses said he could be seen riding in town on his scooter wearing makeup and costumes.
Lucero was pronounced dead at the scene. Gulzow was seen riding down a nearby street on a scooter, according to a probable cause statement obtained by FOX31. The 37-year-old was arrested later that morning and was found with his clothing still covered in blood.
When Gulzow was interviewed by police, he claimed Lucero threatened him to “get out of my alley,” leading to a fight in which he might have accidentally stabbed him, which did not match with witness statements.
