The father of a 1-year-old boy was arrested on first-degree murder Monday after his live-in girlfriend told investigators he punched the child during a profanity-laced tirade.  

East Baton Rouge Parish Sheriff's investigators say Terence Ransom, 33, was booked on counts of first-degree murder, cruelty to juveniles and domestic abuse battery. 

The East Baton Rouge Parish coroner's office said Monday that Josiah Crockett died on Saturday of multiple blunt force injuries to the chest and abdomen. The child's biological mother, who has been in jail for second-degree murder since 2017, gave birth to the child a year ago Sunday.

The incident took place Saturday at a home in the 6500 block of Hanks Drive, according to booking documents. Deputies responded to a call from EMS about an unresponsive infant. Emergency personnel took the child to Our Lady of the Lake North Emergency Room but he could not be resuscitated.

Josiah suffered multiple bruises and injuries the attending physician said are “consistent with physical abuse,” according to the Sheriff's Office.

Shanta Parker, 29, Ransom’s live-in girlfriend, told deputies she had left Josiah on the bed alone in the bedroom when she heard the child “screaming and crying.” She returned to the bedroom to find Josiah on the floor, with Ransom standing over the infant “yelling profanities at him.”

Parker picked up the baby and carried him to the living room to take care of him when Ransom came up behind her and punched both her and the child once on each side of their bodies.

Records indicate Ransom and Parker were booked into East Baton Rouge Parish Prison on Saturday on distribution or manufacturing of Schedule 1 drug, illegal carrying of weapons with drugs and possession of drug paraphernalia. Ransom was booked on an additional count of illegal possession of stolen firearms.

Deputies interviewed an anonymous source who said the child had stopped breathing earlier in the day while Ransom and Parker were “getting high,” and added that the two sell narcotics.

Authorities searched the home and seized two handguns, two clear plastic bags they suspect contains marijuana, a box of plastic bags and a digital scale they believe were intended for the distribution of marijuana.

Department of Children and Family Services spokeswoman Heidi Rogers Kinchen confirmed Monday afternoon that Jimeelah Crockett, who is currently awaiting trial on a second-degree murder charge, is the boy's mother.

Crockett is accused in the 2017 fatal shooting of 38-year-old Joseph Bunch III, who she was dating at the time.

Crockett was booked in September of 2017, according to the East Baton Rouge Sheriff's Parish Prison records, and has never been released. The baby was born May 5, 2018.

According to files from the 19th Judicial District Court, Crockett was scheduled to go to trial this week on second-degree murder charges but had her trial pushed back to September.
