The stepfather of the five-year-old boy pulled from a river in south Wales has appeared in court on Thursday accused of his murder, while the child's mother and a boy, 13, have been charged over his death.
Logan Mwangi, also known as Logan Williamson, was found with multiple injuries, including a torn liver, an internal head injury and a broken collarbone.
He was found in the Ogmore River near Pandy Park in Bridgend on Saturday after police were called to a report of a missing child.
Logan, pictured below, was taken to the Princess of Wales Hospital, where it was confirmed he had died.
John Cole, 39, appeared at Cardiff Magistrates' Court charged with murdering his stepson as well as perverting the course of justice, and stared at the floor throughout the hearing, wearing a grey prison tracksuit.
Logan's mother, Angharad Williamson, also appeared in the dock charged with perverting the course of justice in relation to his death. She too hung her head and did not look up.
A 13-year-old boy also appeared at the same court charged with the same offence and was remanded to local authority care.
Both adults have been remanded into custody and all three, who only spoke to confirm their names and addresses, will appear at Newport Crown Court on Friday.
Detective Chief Inspector Mark O'Shea, the senior investigating officer, said: "This is a very harrowing case for all involved and I extend my deepest sympathies to Logan's family and friends.
"This remains an extensive and sensitive investigation by the Major Crime Investigation Team and I am grateful to the local community for its support and understanding while we have continued to gather evidence across several scenes.
"We continue to appeal to anyone who has any information in relation to the incident to contact the Major Crime Investigation Team."
Family friends have paid tribute to Logan, who they described as "kind, funny, polite, handsome and clever", on social media.
Those wishing to pay their respects were asked to place teddy bears at a lamp-post and footbridge near the scene, just 400 yards from Logan's house.
People arrived throughout Sunday and Monday to lay flowers, tributes, toys and teddies in front of the police cordon by the river. Many of those who came to lay tributes said they did not know Logan or his family but travelled to the area after hearing news of his death.
