Nothing has been revealed: we don’t know if the perpetrator knew the victim. So we don’t know if this was an honor killing or a random jihad. We don’t know if it is a manifestation of the culture of violence that arises from the divine sanction given to the beating of women “from whom you fear disobedience” (Qur’an 4:34) or of the Qur’an’s command to “kill them wherever you find them” (2:191, 4:89; cf. 9:5), but it’s likely to be one or the other.
