Marty Tankleff grabbed the phone and called emergency.
‘Please… hurry!’ the 17-year-old said, rattling off his address to the operator.
But she couldn’t make out what he was saying and told him to calm down.
It was around 6am on September 7, 1988, and Marty explained he’d just woken to find his adoptive father, Seymour, 62, in his study, covered in blood.
He’d been beaten and his throat had been slit.
‘He’s gushing blood,’ Marty said, trying to administer first aid to his father, who was barely breathing.
