Orange County Sheriff's deputies say a couple beat a 3-year-old child to death because he peed his pants.

Robin Greinke, 26, and Steven Neil, 33, were arrested Thursday night on charges of child abuse, first-degree murder and child neglect.

Investigators said on Feb. 28 the couple punched and struck the boy for more than an hour after he urinated on himself.

"They were upset with him and they tossed him and spanked him and punched him," said Chris Dillon, a homicide investigator.

After the attack subsided, deputies said Neil and Greinke then ordered pizza and watched a movie.

It wasn't until around 5 a.m. on March 1 that the couple called 911. Greinke told investigators she made the call because her son was wheezing and she couldn't sleep.

When paramedics arrived, they performed CPR but were unable to save the child.

Initially doctors thought Meningitis was the cause of death. However, after an autopsy, medical examiners attributed the child's death to physical trauma.

Neil and Greinke both confessed to drinking beer and hitting the child numerous times.

Deputies said Neil has a history of abuse with both women and children.

The child would have turned four years old in May.
