Troy Johnson was murdered last Saturday.
The woman suffered a cut on her hand and fled to a nearby restaurant for help. There, she called Polk and he mentioned that he “beat up” Johnson. Polk then met up with the woman and returned the knife, which had been cleaned of blood. The woman went to police after seeing photos and videos of herself on TV and realizing the extent of the situation.
The police are currently in possession of surveillance footage from the train and Polk is being held for murder in the first degree.
Troy Johnson, the man stabbed to death on the Red Line Saturday, was trying to help a man being held up at knife point, prosecutors said. That man’s attacker turned on Johnson and allegedly stabbed him. https://t.co/r6wiMAjZzT
