Brisenia Flores was gunned down at point-blank range in her own home in Flores, Arizona, as her terrified mother Gina Gonzalez, who had also been hit, played dead on the floor.

She sobbed as the court was told how she had heard Brisenia’s desperate pleas as her killer stood over her.

‘I can hear it happening,’ Mrs Flores told the court describing how her daughter said: ‘Why did you shoot my dad? Why did you shoot my mum?’

‘I can hear her telling him to “please don’t shoot me.”’
