Investigate the death of a police officer and his wife

You are assigned to investigate the death of a police officer and his wife who died as their car spun off the road on New Years, hitting a tree in the early morning.  When the toxicology comes back 6 weeks later it shows the husband, who was driving to be positive for cocaine.

• How will you proceed with this information knowing there are two small children surviving their parents and a pending $600,000 life insurance payout?
• Please do a little research here and find a toxicology report first, and if possible, a “tox report” for a MVA death due to the influence of cocaine.
• Why did you make the decisions you made?
