How much does a serial killer make?

Serial killers come from all levels of society. Very few have a lifestyle that enables them to earn high salaries. Very few have a lifestyle that exposes them to public scrutiny as a rich person might experience.

The majority of serial killers have come from ordinary, everyday jobs, menial or part time jobs, or little regular employment.

Placing an income range for a serial killer isn't possible since serial killers operate in different societies, countries, and time periods.
