Murder not likely. Murder does require a particular
specific intent; while I'm not familiar with the niceties of the various US states' rules on that, and much as I despise street racers, I'm not sure that I'd see that requirement being met in the case cited. Manslaughter, quite undoubtedly.
Oh, heck, I might be wrong on that even when it comes to Canadian law, now that I think.
Canadian law says -- and all those "means to (do something)" are the "intent" requirements:
Murder, Manslaughter and Infanticide
Murder
229. Culpable homicide is murder
(a) where the person who causes the death of a human being
(i) means to cause his death, or
(ii) means to cause him bodily harm that he knows is likely to cause his death, and is reckless whether death ensues or not;
(b) where a person, meaning to cause death to a human being or meaning to cause him bodily harm that he knows is likely to cause his death, and being reckless whether death ensues or not, by accident or mistake causes death to another human being, notwithstanding that he does not mean to cause death or bodily harm to that human being; or
*(c)* where a person, for an unlawful object, does anything that he knows or ought to know is likely to cause death, and thereby causes death to a human being, notwithstanding that he desires to effect his object without causing death or bodily harm to any human being.
It's that last bit that would potentially apply. Like, killing someone by burning down a building without bothering to find out whether anyone was in it. I wasn't thinking straight, was I? If drag racing on the street is illegal, then killing someone while driving on the street as participation in an illegal drag race would seem to qualify as murder. ;)
Now ... can I see this applying to someone who illegally lends a firearm to someone else who uses it to kill someone, or illegally fails to take proper precautions to prevent a firearm from being stolen by someone who kills someone, or illegally carries a firearm around in public and has it taken from him/her and used to kill someone ...? Hmm.
