Got the bones of the story of what actually happened to Sada today.
Punter forced her at knifepoint to swallow a bottle of doped drink. She collapsed, was stripped and tied to the bed by arms/legs. He raped her. Punter was disturbed when a friend started hammering at the door as Sada was supposed to be meeting her. Punter ran, leaving a overdosed syringe stuck in her arm, luckily he'd been disturbed before completing the injection.
Next day Birmingham police rang, trying to find her. They wanted to know why the guy they'd just arrested for murder had her ID card in his pocket. He'd carried out an identical attack, but this time completed the job of killing the girl.
Got put away for 24 years - I presume a life sentence tariff.
