Morgan was found guilty of murder earlier this month at Swansea Crown Court. He will serve a minimum of 19 years in jail.
“The violent shaking with Jensen-Lee’s head moving back and forward quickly accelerating and decelerating may have been very brief but it was hard enough to cause his extensive internal head injuries that caused his death,” said the judge, Mrs Justice Stacey.
Morgan had claimed throughout the trial, and until his eventual arrest in July 2025, that the injuries were caused as he tried to save the baby from choking to death.
He attended Jensen-Lee’s funeral and cremation on 24 May, 2024. Members of Jensen-Lee’s family were interviewed by police as the full extent of the baby’s injuries became apparent to police.
He was not arrested on suspicion of causing the injuries to Jensen-Lee until July 2025.
During the four-week trial the jury heard how Morgan was regarded as Jensen-Lee’s stepfather after starting a relationship with the baby’s mother, Jordan Dougal in December 2023, and moving into the family home in January 2024.
Dougal said her son was “a really happy baby” and that she “never had any issues” with Morgan caring for her son, adding she thought she had found their family.
Morgan was left alone with Jensen-Lee at the family house in Clydach, Swansea, while Dougal went to work on 30 March 2024.
The jury heard how Morgan claimed he feared the baby was choking on his own sick and put his fingers in the baby’s mouth to remove any blockage. He said Jensen-Lee’s body had seemed limp when he picked him up and so he “shook him”.
