A man who was wearing claw-like gloves and clown-style makeup when he allegedly stabbed another man to death in Denver has been charged with first-degree murder.

Christian Gulzow, who was formally charged Thursday, was arrested May 23 after surveillance cameras helped officers track him down.

Witnesses told police that a man with white clown makeup with black streaks threatened 29-year-old Brian Lucero in a convenience store and took swings at him with his gloves, which had blades about 3 inches (7.6 centimeters) long at the end of each finger. They say Lucero walked away, and the 36-year-old Gulzow followed him to a nearby parking lot.

Police say Lucero collapsed in the lot, and Gulzow fled on a scooter.

Booking documents do not indicate if Gulzow has hired an attorney.
