In 2019, the Offender Database recorded that Marina Tilby, then 26, of Llwyncelyn, Aberaeron, Ceredigion, was jailed for the “deliberate neglect” of her four-week-old son, Darian, who died after she drunkenly fell asleep on him. On appearing at Swansea Crown Court for sentencing, the court reported that the incident took place at a holiday park in New Quay, Wales, in March 2017.
The investigation established that Tilby had spent the night drinking and dancing at a bar, where witnesses saw her repeatedly throwing and catching her infant son. Dyfed-Powys Police reported that she later took Darian back to a caravan with two men she had met. The prosecution reported that in the early hours of 31 March 2017, the baby was found unresponsive with blood in his mouth, lying next to Tilby, who was so intoxicated she could not be roused for over an hour.
Judicial Findings and Investigative Detail
The court reported that while medical evidence could not definitively prove that Tilby rolling on her son caused his death—ruling out sudden infant death syndrome was not possible—the neglect was undeniable. Swansea Crown Court heard how Tilby had prioritized her night out over her duty to protect her four-week-old child. The prosecution reported that Darian was taken to Bronglais Hospital, where he was pronounced dead, and it remained unknown if he could have been saved had Tilby raised the alarm sooner.
Judge Paul Thomas branded the case a “dreadful instance of maternal selfishness.” For her actions in New Quay, Wales, Tilby was told that she had shown a deliberate disregard for her son’s welfare by getting so drunk she fell into a deep sleep on top of him. The judge noted that the custodial sentence of two years and four months was necessary to reflect the gravity of her failure as a mother and the tragic consequences of her intoxication in Ceredigion.
