Super rare female spree shooter kills four in Houston

This shooting took place on April 7th, but the fourth victim just died today. This might be the deadliest single perpetrator female spree shooter since 2006.

Dekitta Holmes shot her sister in Fresno, TX, then drove to Houston and shot her mother, stepfather and another unidentified man.

Holmes shot herself afterward.

With four people dead, this shooting is in a seven-way tie for the third deadliest spree shooting of 2017 so far. However, it is by far the deadliest rampage carried out by a female.
