A man accused of killing his former girlfriend in a Parkville apartment over the weekend remains in custody Monday. Baltimore County police said officers arrested Rashard Mack, 23, of Baltimore, on a first-degree murder charge on accusations he killed Taejhiana Walker, 22, of New York. Mack declined legal help until he appeared before a judge Monday for a bail review. He requested a postponement to Tuesday so he could get representation from the public defender's office. Police said officers were called around 1 p.m. Saturday to the 8300 block of Nunley Drive in Parkville for a domestic dispute that escalated into a stabbing. Walker was stabbed multiple times and died at the scene. Mack was also injured.
