Meanwhile Tony is building a profile of likely abductors. He rules out the first police suspect: a paedophile recently re-homed on the estate. The man prefers boys but as public anger rises he has to sit in a police holding cell for his own safety. Meanwhile, a distraught mother, Celeste comes forward identifying the missing girl as her daughter Janita. She should be safely at school, but neither she nor her young friend Mikey turned up. Celeste is stricken because Janita's twin died in infancy. Is she going to lose another child? Tony knows that a likely abductor will know the area and know his escape routes. But searches produce no matches. And although she struggled, the abducted girl had her chance to run but didn't take it. So was the abductor a stranger, or someone she knew after all? Janita's father and step-father both have alibis. When Janita's friend Mikey, the last person to have seen her alive, is found trying to burn his blood-stained school uniform he also enters the frame as a possible suspect. But Mikey refuses to talk.
