Miki Hatcher, 23, of Chocowinity, North Carolina, was killed on July 3, 2010 in the apartment she shared with her boyfriend, 21-year-old Richard Leon Armstead. Reports say the couple had been engaged in continuous fighting that escalated in the days before the killing. On the evening of July 3 Armstead inflicted fatal wounds to Hatcher’s head, and he then fled to an apartment in Greenville where police arrested him after a three-hour standoff.

Armstead had prior convictions for common-law robbery and wanton injury to personal property in Martin County and had been released from prison in April 2009 after serving an 11-month sentence. Hatcher and Armstead had two young children together, making the loss to their family particularly acute.
