Hello sir, the question is Mila, who is 85, is in the supermarket on a busy Saturday afternoon when she begins to feel pains in her chest. It transpires she is having a heart attack and she collapses to the floor. Although the supermarket is crowded, no one comes to help her.

Brian, the store manager, puts a call out over the PA system asking if there is a doctor present, but otherwise offers no assistance. Hearing the announcement, Karen, a nurse, comes forward and tries to help Mila, but fails to put her in the recovery position. Mila later dies.

Meanwhile, some youths see Milas car, which was left unlocked and with the key still in the ignition in the supermarket car park as she did not want to spend time looking for a parking space. The youths drive off in the car, failing to stop at a pedestrian crossing, hitting Jill and her daughter Heather who were crossing the road. Both are injured, Heather seriously. One of the youths, Luke, who was not wearing a seatbelt, suffers a serious head injury.

Advise the parties. How to explain sir ?
