Farmington • Prosecutors have until Friday to decide whether they will seek the death penalty against a Layton man accused of beating his girlfriend's 2-year-old son to death over potty training issues.

Joshua Schoenenberger, 35, is charged in 2nd District Court with first-degree felony aggravated murder and second-degree felony child abuse for allegedly inflicting fatal injuries last year on James "J.J." Sieger Jr.

Schoenenberger was in court Wednesday for a brief hearing, where his attorney, Edward Brass, told the judge that they were waiting for prosecutors to decide whether they would seek his execution. The statutory deadline for making that declaration is 60 days after a defendant pleads not guilty, which Schoenenberger did on April 11.

He was charged with aggravated murder under "Shelby's Law," a 2007 statute that allows prosecutors to seek the death penalty if a child dies during an act of abuse, sexual assault or kidnapping — even if the defendant does not intend to kill the victim.

Schoenenberger will be in court again on June 27 for a scheduling conference.

Layton Police Detective Ryan Jeppson testified during a January preliminary hearing that Schoenenberger offered police a variety of explanations for how the toddler suffered what proved to be fatal blows to his stomach and bruising all over his body.

Schoenenberger initially told police that he had left the child alone in the bathtub for 40 minutes on May 9, 2015, and then found him face-down in the water.

The man then flipped his story, saying it was his girlfriend, 24-year-old Jasmine Bridgeman, who had been left alone with the child.

Then, he said, it was Bridgeman who "beat" the child.

But Jeppson testified that Schoenenberger eventually admitted to police that he had inflicted the injuries, allegedly admitting that while taking a shower with the young boy, he picked him up, squeezed him hard and then dropped him.

"He was upset about, essentially, J.J. not listening to him," Jeppson testified. "[And that] J.J. was struggling with potty training."

Jeppson also testified that Schoenenberger was visibly upset as he told police that the boy, who died two days after he was taken to the hospital, had been removing his diaper and spreading feces on the walls.

Bridgeman was charged with second-degree felony obstruction of justice for lying to police as they investigated her son's death. She was sentenced in April to a one-to-15 year prison sentence after pleading guilty to the charge.
