Jurors are going into a fourth day of reviewing evidence and testimony in the manslaughter trial of Kelli A. Jacobsen.
The 12-member Benton County Superior Court panel spent another 61/2 hours Thursday in deliberations without reaching a verdict.
So far, they've spent about 16 hours total locked up in a jury room. The case went to the jury of three women and nine men at 12:25 p.m. Tuesday.
Jacobsen, 28, is accused of causing head trauma that killed Ryder Morrison.
She was the live-in nanny for the 1-year-old Richland boy, who died June 22, 2011, after he was rushed to Kadlec Regional Medical Center.
Thursday afternoon, the jury sent out a question: "When there is a series of reckless acts, is it the person performing the last reckless act that is guilty of man 1?"
Judge Vic VanderSchoor again advised the panel to rely on its collective memory of testimony, their notes and jury instructions.
Deliberations continue Friday.
