Authorities are investigating after a baby boy found in medical distress in a South Los Angeles motel room died this week, police said Wednesday.

Hospital staff notified child abuse detectives of the 18-month-old’s death around noon Tuesday, the L.A. Police Department said in a news release.

Coroner’s officials identified the boy as Dee’ago Alexander Jones.

Jones had been in medical distress when he was transported from the motel on the 5600 block of Western Avenue in the Chesterfield Square neighborhood and was pronounced dead at the hospital, LAPD said.

“They said he was alive when he made it to the hospital but he really wasn’t, he was already gone,” Jones’ mother, Ryanna Jones, said.

Ryanna Jones says her baby was happy and healthy one minute, then she later came home and he was unconscious and unresponsive.

The mother says the boy’s father confessed to killing his son after tripping over a video game controller. He then punched the child, who fell to the ground, hit his head and lost consciousness, Jones alleged. 

Ryanna turned in her son’s father, 23-year-old Shane Zachary Flowers, over to police.

“If you guys are in an abusive relationship then I suggest you leave because this is the outcome I got, my baby gone because of him,” the mother said.

Surveillance video captured across the street shows paramedics loading the child into an ambulance.

His cause of death had yet to be determined. A coroner examination will ultimately determine if charges are filed against the father.

LAPD said officials are not identifying any person of interest in the case.

This investigation remains ongoing, and no further details were available.
