But instead of phoning an ambulance she called her estranged husband. When he failed to arrive by 3pm she left to collect the children from school. She arrived home 10 minutes later and told Sean's sister he was dead. Eventually her estranged husband Michael Allen arrived. He called an ambulance at 3.27pm - 42 minutes after the baby had been discovered dead. Coroner Dr Elizabeth Stearns recorded an open verdict, saying Sean had inhaled his own vomit and died, but she did not know why.
