This was an obvious scam and pfishing expedition. The caller said "that a process server was going to arrive and serve my wife with a summons. No names, no details, no complaint, no nothing. Just a threatening tone of voice that was as fake as his reason for calling. This jaybird should be jailed and waterboarded at the very least!! No wonder nobody wants to answer the phone these days. I told this character if he showed up, he would be met with my shotgun. No more calls....
