Two Chicago heroin dealers have appealed their convictions for causing overdoses, one of them fatal, in Sioux Falls.
Judges from the Eighth Circuit Court of Appeals heard arguments in the combined cases on Tuesday, Dec. 15.
Defendants say the affected drug users had an assortment of substances in their systems.
But the U.S. Attorney for South Dakota says the overdoses would not have happened if not for the heroin.
Victoria Wicks has more on this case for SDPB.
