DOYLESTOWN, Pa. (CBS/AP) — A jury in Bucks County says it can’t come to a unanimous decision on whether to sentence a man to death for raping, strangling and dismembering his girlfriend’s 14-year-old daughter. Jacob Sullivan pleaded guilty to first-degree murder and related charges in the 2016 slaying of Grace Packer.

After nine hours of deliberations over two days, jurors told the judge Wednesday afternoon they’re deadlocked.

The judge told jurors to keep deliberating. If the jury can’t come to a unanimous decision, Sullivan will automatically get life without parole.
