The Sex Slave Murders of Sacramento

Sacramento, California has seen a fair share of gruesome crimes during the 1970s and 1980s. That city was the hunting ground of the Original Night Stalker who is still unidentified until this day. Richard Chase was also active in the area and he was nicknamed the Vampire of Sacramento due to the uncommon ritual which included drinking the blood of his victims. So when Gerald Gallego and his partner in crime Charlene Gallego embarked on their rampage of kidnapping and killing young teenagers, they were just a couple of many depraved criminals who were on the search for the next target around the capital of California.
What made Gallego so terrifying was the fact that he had an accomplice who lured in the teenagers he had selected and the way he committed the killings by having a complete control over them. The Gallego case once again sparked the debate about what makes a serial killer and are some people more prone to violence than the others due to their genetics?
