TROY — The Rensselaer County jury deciding the quadruple-murder trial of James White is deadlocked as it heads into a fourth day of deliberations, raising the possibility of a mistrial.

The jury of six women and six men has been deciding White’s fate for more than 12 1/2 hours since getting the case Tuesday afternoon. The panel will return to court Friday at 9 a.m.

On Thursday, jurors sent a note to County Judge Debra Young informing the judge they could not reach consensus on any of the charges facing White. The judge read the jury an “Allen charge,” an instruction to push a deadlocked jury to continue working to reach a verdict.

If jurors do not reach a verdict and continue to inform the judge they are deadlocked, Young could declare a mistrial, which would mean the trial would have to be rescheduled.

On the night of Dec. 21, 2017, White and Justin Mann rode bikes to a CDTA bus stop in Schenectady, places the bikes on bus and commuted to Troy. The pair went to a basement apartment at 158 Second Ave. in Lansingburgh where, prosecutors allege, White placed a pillow besides the victims’ heads and plunged a knife through their necks.

The victims include Brandi Mells, 22; Shanta Myers, 36; and Myers' two children: Jeremiah Myers, 11, and Shanise Myers, 5,.

Mann, who admitted he tied up the victims, pleaded guilty to four counts of second-degree murder and agreed to become a witness for the prosecution. He faces 25 years to life in prison.

White, who testified Monday, alleged Mann committed the murders.

Jurors on Thursday reheard testimony, read back by a court reporter, about blood found on White’s gloves. The gloves had DNA consistent with Shanta Myers, Shanise Myers and White.

White faces nine counts of first-degree murder, each of which carries a sentence of life in prison without parole, as well as second-degree murder charges.
