I am writing a fictional novel and hope to get some advice! In my novel, a drunk driver gets in an accident that kills a young couple and leaves their 12-year-old child orphaned.

The driver comes from a wealthy Massachusetts family and helps him to buy a lighter sentence. After killing 2 people, he serves one year in jail. He must also provide a settlement of sorts to the orphan, to be paid out when she is of age. The orphan ends up being raised in foster care and learns of the settlement upon her 18th birthday.

Would something like this ever happen - specifically with the establishment of a trust fund to an orphan to reduce jail time? If so who would broker the deal- the prosecutor?
