Remember, the EMT's were only able to restart Max's heart
after 2 successive injections of epinephrine. Due to Max's vomiting and the need to continually suction his airway, they were unable to effectively perform CPR, they were also unable to intubate him.
Max's vomiting, along with concern about protecting his injured neck/spine made CPR pretty much impossible.

The fact that Dr. Peterson didn't know RZ would die isn't germane. What is unusual is that he felt the need to contact LE about his incorrect diagnosis of Max's problem after RZ was dead.
What would be the point of asking LE to investigate her if she was dead?
Did Dr. Peterson think someone else was responsible for causing his erroneous diagnosis of Max - suffocation?
When and how many conversations did Dr. Peterson have w/ the Shacknai/Romano family members about his erroneous diagnosis before reporting it to LE 4 days after the accident?
How can anyone claim RZ committed suicide because she was under investigation for child abuse when the Dr. didn't report anything to LE until after she died?
