A man killed his girlfriend and their 10-month-old daughter in a "sustained and fearsome" knife attack in Hampshire before fleeing and leaving the couple's other young child locked in the house, a court has heard.
Anthony Marsh plunged the weapon into half-naked Stephanie Bellinger, 24, more than 30 times in the bedroom of their home in Totton, Winchester Crown Court heard. Their daughter Lili Marsh was stabbed once through the head as she lay on the same bed.
But unemployed pub worker Marsh, 22, did not kill the couple's two and half-year-old son during the attack in February this year.
Marsh instead fled the house, locking the boy in for 30 hours until his worried grandmother, Elizabeth Bellinger, and Ms Bellinger's older sister, Ruth Goody, broke into the house and were confronted by the "truly distressing scene" that was "gruesome to behold".
Christopher Parker QC, prosecuting, told the jury that the pair found their relative naked from the waist down on the bed with her night shirt pulled up over her body. Marsh had also thrust the knife into his girlfriend's mouth and left it there.
He denies murder, but admits the killings on the grounds of diminished responsibility.
Marsh was arrested a few days later in nearby Fareham and told police in interview he heard voices telling him to kill Ms Bellinger as they lay in bed together.
He said he went downstairs, got a kitchen knife and attacked his sleeping partner by plunging the knife into her neck after counting to 50 several times and he repeatedly stabbed her as she screamed. He then said he tried to suffocate Lili, because the voices told him to, with the duvet and by standing on her but she was still breathing. He said he could not remember stabbing her.
He told officers he then took a shower and cuddled receptionist Ms Bellinger and the voices told him to kill his other child but he was able to resist them.
Mr Parker told the jury that Marsh had been diagnosed with bipolar disorder after taking a large amount of drugs in his teenage years but he had never mentioned hearing voices to doctors
