Set-up a website "w w w .pleasedontkillrobwiggin. c o m", and then publically post rob wiggins:
Full name, w/ copy of his birth certificant
Driver's license number
current address
cell phone number
names, address, phone numbers and other identifying information of his family member including:
parents, siblings, wife, wife's family, friends, extended family members, women he's dated in the past, women that have claimed he has abused them in some way, the names of the people he was incarcerated with and their identifying information, etc...
Post big color pictures, Google maps of his current address, with pictures of his house, his children, their schools, what vehicle(s) he's driving, with license plate numbers, the address of his favorite bar, favorite restaurant, the fat cow he's cheating on his wife with and all of her information, etc...
Use mass emails and offer unreal (and false) amounts of reward money to continue to gather more information. The site may get taken down, so be ready to move it around under other names and (obviously) foreign hosting. And let him know that all he has to do to make you go away is sign over his website to you. Oh, and $10,000 in cash, too.
