Most murders where the killer and victim are of the same race tend to be "crimes of passion" while inter-racial murders are usually "felony murders;" that is to say, murders which were perpetrated during the commission of some other felony (most commonly either armed robbery or forcible rape), the point being that juries are more likely to impose the death penalty in cases where the offender has killed a total stranger than in those where some deep-seated, personal revenge motive may be present.
