2007
January - Peter is returned to his family.
June - Barker's brother, Jason Owen, moves into the home with a 15-year-old runaway he describes as his girlfriend.
July 30 - Maria Ward, a social worker with Haringey Council in north London, makes a pre-arranged home visit. She misses injuries on Peter's face and hands after he is deliberately smeared with chocolate to hide them.
July 31 - Police hand reports to the Crown Prosecution Service, including statements from two doctors saying Peter's bruising was suggestive of "non-accidental" injury.
Prosecutors decide there is not enough evidence to bring a case.
August 1 - Peter is taken to a child development clinic at St Ann's Hospital in Tottenham, north London. Paediatrician Dr Sabah Al-Zayyat decides she cannot carry out a full check-up as the boy is "miserable and cranky". A post-mortem examination later reveals Peter had probably already suffered a broken back and fractured ribs by this point.
August 2 - Police tell Connelly she will not be prosecuted. That evening, the child receives the fatal last blow to the mouth, knocking his tooth out.
August 3 - A 999 call is made at 11.36am. Four minutes later paramedics find Peter lying in his blood-spattered cot. He is pronounced dead on arrival at hospital. An attempt has been made to cover up the crime, with the child's clothes and bedding removed and dumped.
