Hypothetical Trial against a non-vaccinated family. You're the jury.

A 9 month old girl is infected with measles and dies because her neighbors were unvaccinated, unbeknownst to the girl's parents. After becoming ill from direct contact with the boy next door she becomes I'll and it is tracked by the local health department as being contracted from the unvaccinated neighbor child. The girl developed encephalitis and perishes. For the first time, the state and local health authorities team up and charge the parents with negligent homicide, child endangerment, and child neglect. You're on the jury. Your verdict would most likely be?
