Records show the person to whom Markoff owed the $10 was also one of the last people to call him before he was shot.
Police have already said they believe Knight provided the gun for the shooting, but that the 15-year-old juvenile actually pulled the trigger. Police have also said two other people apparently waited down the street in a vehicle when the shooting happened.
Police also said information technology, such as social media, helped police develop the suspects in the murder.
