Baltimore's former public enemy number one will head to court Tuesday morning for a preliminary hearing.
Christopher Straham is accused of stabbing a 73-year-old homeless man to death on Pulaski Highway early last month.
He is charged with first-degree murder, second-degree murder, robbery and assault.
Last summer, the 19-year-old was accused of threatening someone with an illegal knife. That case was never prosecuted and the charges against Straham were dismissed.
