A male rapes his 18 year old, developmentally disabled stepdaughter, and she is later found dead. The cause of death is that her throat was cut, after which the house she was in was set on fire and her uterus was cut from her body to hide the evidence of the stepfather's crime. The girl's mother is suspected in the murder, as the stepfather was in jail at the time.
A mother killed her pregnant daughter, and then cut out her daughter's uterus to prevent her child molesting husband out of jail. Of course, since the crimes committed did not involve a firearm, that is is just fine with the anti-gun people, as it is not a "gun related crime" and thus does not matter.
