It is *possible* that he could get hit with the felony murder law, whereby if someone's death can be directly attributed to your actions while you are in the process of committing a felony, you are charged for their murder.
However, again, the responsibility for operating the choppers rested on the pilots themselves, and since a chopper crash isn't (previously... I guess now it is) a foreseeable consequence of a ground-driven police chase, it would be massively difficult to convict this guy for anything relating to this crash.
Any damage or crashing that occurred on the streets during his chase, however, is all on him.
