Gary Ridgeway has pleaded guilty to killing at least 48 women. He is now the most prolific serial killer in US history. Part of his statement: He has received a punishment of 48 counts of life without parole and a fine of $480,000 - $10K for each of his victims. Keeping him incarcerated will cost US taxpayers around $40,000 - $50,000 a year. Does he deserve to live?
