A Criminal Court jury deliberated all day Thursday, but could not reach a unanimous verdict in the case in which Temekia Reed is charged with stabbing a 15-year-old girl to death with a pair of scissors.
Judge Rebecca Stern declared a mistrial at the close of the day.
Attorneys will later pick a new court date.
Ms. Reed is charged with first-degree murder in the Dec. 19, 2011, death of Shaviya Vinson during an altercation that was allegedly over an unpaid $20 babysitting fee.
