Angharad Williamson, 31, claimed that her partner of 6 feet 4 inches, John Cole, 40, hit Logan Mwangi twice in the stomach 3 feet 5 inches, causing him to land hard on the floor. Williamson told jurors in Cardiff court that after Logan picked up a 14-year-old boy, who could not be identified for legal reasons, he dragged Logan off his feet and pushed the child’s head to the floor. Cole, 40, Williamson, 30, and the 14-year-old boy deny killing Logan, whose body was found in a river near his home in Sarn, South Wales on July 31 last year. He had suffered more than 50 injuries, including severe internal injuries to the stomach area. Williamson claimed that Cole attacked Logan after the couple had an argument over damage to a stereo. He said: “It escalated very quickly. I was talking to Jay [John] in the kitchen as there was my stereo and immediately said, “It could be Logan.” I said, ‘Why do you always blame Logan?’ He said, ‘Stop shouting, when women are shouting, people are calling the police.’ ; “ Jay said Logan was smiling and told him, “You like it when your mom and I fight.” He pulled Logan down the aisle. she tried to talk to him and Logan stuttered and did not talk to Jay. I said, ‘Leave him alone,’ but he said, ‘No, I’m fed up, he has to talk to me.’ “Logan stuttered again and Jay hit him twice in the stomach and hit him on his bum and hit his elbows on the floor.” Williamson said Cole prevented her from helping Logan, who got up. He told the court that Cole told the young man, “If he gets upset or stutters again, wipe him.” Williamson said this was a martial arts move, wiping an opponent’s feet. Logan’s mother said the young man obeyed and swept the little boy off his feet and pushed his head to the ground. The court heard Williamson that Logan did not appear to be in pain or discomfort the day before his body was found, although he had refused to eat his favorite meal with pizza and chips on Friday night. She said after putting him to bed that she took her medication and went to bed around 10pm. When he woke up around 5.30am, Logan was not in his room and started looking for him around the apartment and outside, eventually calling police, Williamson said. Peter Rouch QC, defending Williamson, said: “The prosecution suggests that what happened then was a fraud by you and a pretense. It is true that?” Williamson said: “You can not pretend such feelings. I was so scared. My worst nightmare had come true. He had gone. “He was my little boy and he was out there alone.” Rouch said: “When you got up in the morning, did you know what had happened that night? “Is John Cole taking Logan’s body to the river?” Williamson said, “No, I did not.” Williamson previously told the jury that Cole was “strict” with Logan and would let him stand in a “naughty corner” for up to 30 minutes at a time. He said: “I thought Jay was trying to help the family get structure. “I did not realize how strict he was and how scared Logan was.” Cole admitted to taking Logan’s body from the apartment in the early hours of the morning and leaving it by the river, but says he did not know how the boy died. Williamson denies any involvement in her son’s death, saying she slept through the night and woke up to find him ignored. At the beginning of her proof she described Logan as the “perfect baby”. He said: “I loved the bones of this boy. Logan was my little helper. We did everything together, a happy little boy was so beautiful. “He was so smart, he wanted to explore the world and see what was going on and I was so proud, so proud.”
