According to a criminal complaint, police were called to Kartak’s apartment complex on March 29 after a report of someone roaming the building with a large knife, covered in blood.

When police arrived, they found Johnson unconscious with a large knife near his feet. After police took him into custody, he made incoherent statements about “spirits and ghosts.” A blood-alcohol test revealed Johnson’s BAC was .18.

Kartak’s body was found in his unit. He had suffered multiple stabs wounds.

Witnesses told police that Johnson and Kartak would often drink and use marijuana together. They described the two as longtime friends.
