what is the minimum sentence you could get for driving on a suspended license speeding and wreck and someone is killed in accident in indiana

It would really depends on how it was charged.  There seems to be a couple of offenses that the driver could have been charged with.  The type of Felony/Misdemeanor will really determine what the sentence range will be.  Also, if there are multiple counts, then a defendant could be faced with multiple sentences and these sentences could be ordered to be served consecutively or concurrently.  If you know the charges, update the question and I can give you the ranges for each count.
