A HEARTBROKEN new mum hanged herself, wrongly believing she’d killed her three-month-old daughter, an inquest heard.

Laura Delean was resuscitated after being found unconscious while staying with her partner’s parents in Ranfurly Gardens, Dibden Purlieu.

But an inquest heard how she died two days later, on August 26, at Southampton General Hospital.

The 33-year-old thought she had mistakenly suffocated her baby Cristina at their Sevenoaks home earlier that week, not aware the death was caused by unexplained sudden infant death syndrome.

Ms Delean’s partner Matthew Coleman criticised Kent police for being “very pushy” in their investigations into his daughter’s death, saying they had conducted themselves “terribly”.

He told the inquest: “I would say that had a bearing on it.”

Coroner Grahame Short recorded a verdict that Miss Delean took her own life while suffering from post-natal depression.

Hampshire DS Frank Nelson said he would be contacting Kent Police about Mr Coleman’s complaint concerning their conduct.

In a statement to the Daily Echo, Kent Police said: “The police have a duty to establish the facts around any sudden death, and to collect and preserve evidence which may later assist the authorities,” adding that “every effort” was made to investigate sensitively.
