The man arrested in the Sunday death of his girlfriend’s 1-year-old son beat the boy three times in less than 24 hours and then told the boy’s mother he thought the child was dead, court documents say.

Raymond Parker, 23, said the last time he “whipped” Demarcus Stokes, he used a belt, causing the toddler to hit his head, an affidavit of probable cause says. After that beating, Parker told the boy’s mother, Kimyia Stokes, 22, he thought her child was dead, the affidavit says.

Stokes — who also was arrested in her son’s death — said Parker beat Demarcus three times between Saturday and Sunday, the affidavit says.

The mother saw two of the beatings and heard her son yelling during another, the affidavit says.

Stokes told police Demarcus was breathing irregularly around 1 a.m. Sunday and stopped breathing three hours later, according to the affidavit.

Stokes and Parker dressed the child and “waited around trying to figure out what to do and say” before Parker finally called 911 at 6 a.m., the affidavit says.

Paramedics with East Baton Rogue Parish Emergency Medical Services arrived at the couple’s home at 2627 Erie St., shortly after receiving the call, but they could not revive the child, Baton Rouge police have said.

Police were notified and arrived at the scene moments later.

Cpl. L’Jean McKneely, a spokesman with the Police Department, said Parker hit Demarcus because he wouldn’t sit still for a haircut and the child had urinated on himself during the night.

The results of an autopsy on the boy showed he died of blunt-force trauma to his head, throat, legs and arms, McKneely said.

Police arrested Parker on Sunday and booked him into East Baton Rouge Parish Prison on one count of illegal possession of stolen things after officers found several stolen televisions and more than $16,000 in cash inside his home.

Parker was booked Tuesday on a count of first-degree murder in Demarcus’ death.

Kimyia Stokes was arrested Tuesday and booked into Parish Prison on one count each of second-degree cruelty to a juvenile and accessory after the fact to first-degree murder.

Stokes, who is pregnant with Parker’s child, is accused of knowing about the beating of her son and doing nothing to stop it, McKneely said.

She also is accused of waiting three hours after her child stopped breathing before calling 911.

Tuesday’s arrest of Stokes and Parker was not the first time the couple encountered the police, according to court records filed with the East Baton Rouge Parish Clerk of Court’s Office.

Eight days before being arrested in Demarcus’ death, Parker was booked into Parish Prison on one count of simple burglary for allegedly breaking into a vehicle in the 3000 block of Geronimo Street, an affidavit of probable cause says.

He was released from Parish Prison Oct. 16 after posting a $7,000 bond, prison records show.

Parker served six months in Parish Prison in 2008 after trying to kill his then girlfriend, court records show.

During the attack at a park on Dover Street, Parker told the woman he was going to kill her, put her in the trunk of her car and let his friends rape her, an affidavit of probable cause says.

Parker was convicted of attempted second-degree murder.

A year later, Parker served another six months in Parish Prison for threatening to kill his girlfriend at that time, an affidavit of probable cause says.

Parker told the woman he was going to kill her unless she called his former girlfriend — the one he tried to kill in 2008 — and invited her over to their apartment so he could kill her, the affidavit says.

Parker was convicted of simple assault.

Stokes was arrested in 2007 for allegedly bringing her sister, who was 15 years old at the time, to a Baton Rouge group home so the sister could have sex with a resident, according to an affidavit of probable cause.

Stokes was booked into Parish Prison on one count each of unauthorized entry of an inhabited dwelling and contributing to the delinquency of a juvenile, court records show. The case never made it to court.

In addition to Parker, two other adults living at the Erie Street residence were arrested Sunday and booked into Parish Prison on one count each of illegal possession of stolen things.

Brandon Tate, 30, and Kierra Golman, 21, were arrested after police found the stolen televisions and cash stashed throughout the house, McKneely said.

Three children at the residence were put under the care of Child Protective Services, McKneely said.

Two of the children, 1-year-old twin girls, were found with diaper rash so bad they were bleeding, he said. A 2-year-old boy seemed to be in good condition.

The children’s relationship to Demarcus has not been determined.
