Probably not given her apparent gross indifference to human life in general. Still, someone should ask Chante if she would have helped this man if he was a "brother". If she answers in the affirmative, they should tack on "hate crime" charges as well
She could also try to claim a "temporary insanity" defense because she was under the effects of X (there is supposed to be some truth to being able to be declared "legally insane" after taking a number of hits of LSD; different drug but who knows what her lawyer may try). She won't be successful in any sort of an insanity plea because her no count boyfriend was aware of the situation and denied assistance as well. Has he been charged yet?
