Callan

Four years later and still no body found nor murderer found. The police have given up on the investigation and determined the case to be closed as they had no more leads to turn too. On Callan's first day of senior year, he receives a letter from his brother. Thinking its a prank more than anything else, Callan shoves the letter into his pocket and decides to forget it as he wants to enjoy his senior year. He can't let old ghosts keep him in the past now, well can he?

Or so he thought until he starts seeing his brother everywhere.
