You are called to investigate a crime scene consisting of a house and detached garage. Inside the house, the first responder discovered two dead victims: a man and a woman. Both appear to have died from gunshot wounds to the head, and one handgun is visible at the scene. It is unknown whether they were both victims of a homicide. The witness who called the police reports that the victims were known to have been in a romantic relationship until recently breaking up.

For this part of your report, address the questions below:
