Fla. boy, 3, beaten to death for wetting his pants, say cops

(CBS/WKMG) ORLANDO, Fla. - Police in Florida say a mother and her boyfriend had pizza and watched a movie after fatally beating her little boy for an hour because he wet his pants.

Robin Greinke, 26, and her boyfriend, Steven Neil, 33, were arrested Thursday after the medical examiner determined Greinke's 3-year-old son died of blunt-force trauma and not a medical issue as initially believed.

According to CBS affiliate WKMG, the couple said nothing as they exited interviews with homicide detectives, but investigators said Greinke confessed to beating her son to death.

The Florida Department of Children and Families (DCF) said the two were visiting Florida from Illinois.

Deputies were called to the apartment on March 1, and doctors originally thought the child was sick with meningitis because of his bruises.

An autopsy showed, however, that he had been killed by blunt-force trauma to his head, the Orange County Sheriff's Office said.

"They explained how they tossed the little boy around," homicide detective Chris Dillion told WKMG. "They were upset with him and they tossed him and spanked him and punched him."

Detectives said the pair had been drinking and were possibly taking pills before they attacked 3-year-old Noah Fake for an hour. Detectives said Neil convinced Greinke to wait until the next day to call for help. When she noticed Noah wasn't breathing, they finally called 911.

"The mother admitted, full confession, how they beat the baby and she was very apologetic, but obviously it's too late now. He's gone," said Dillon.

It is not clear whether the child was ever abused before, but there is no record of abuse with DCF. Detectives said the couple had been dating for a year and a half and that Neil's former girlfriends said he also beat them and his own biological child.

Deputies charged Neil and Greinke with first-degree murder, aggravated child abuse and child neglect.
