The husband of murder victims Lisa Clay and her six-year-old son Joseph Chadwick remains seriously ill in hospital this week.
Miss Clay and Joseph were found stabbed to death at their semi-detached bungalow in Bolton-le-Sands on April 9.
Police arrested 34-year-old Paul Chadwick after he was found with self-inflicted stab wounds in the house.
Mr Chadwick is currently being cared for at the Royal Preston Hospital.
Joseph, who attended nearby Bolton-le-Sands Primary School, was found by detectives in his upstairs bedroom where he had been ‘attacked with a knife’.
Lisa was found downstairs, having also suffered fatal knife wounds.
Police launched a murder investigation following the gruesome discovery.
Shocked neighbours, who said the family had only been in the house for a matter of weeks, expressed their disbelief at the news of the double murder.
