If I was a serial killer.
1. Homeless teens (Both genders) and if I could get away with it. Some girls from school.

2. Manual asphyxiation, some light necro, and cannibalization of breasts and genitals.

3. Hair and fingers.

4. Don't need a flashy name. Just something starting with The and ending with Killer.

5. Before strangling them, I would play with some of them depending on how cute they are.
