Angel Killer Read Online Free PDF

would be silly to spend a hundred million dollars developing machines to look through several tons of rubble for bodies. I can assume the other cases probably contain field versions of equipment we have back at the labs or more experimental gear.
    I splash some water on my face and try not to look at myself in the mirror. It doesn’t matter how many people tell you that you look great without makeup, you still notice. Seeing my face from a decade ago on that magazine didn’t help either. I’m still fit from jogging and yoga and get hit on by college guys, but I know youth is a diminishing asset. I’m afraid there’s going to be a point when I start counting the compliments and the looks that I now ignore and feel bad when they come up shorter than before.
    After I broke up with my last boyfriend I caught myself looking on his online profile to see if his new girlfriend was younger than me. She wasn’t. It shouldn’t matter, but it does.
    As I find my way back to my seat, I think about what I’ve seen on the plane and what I know so far. Body. Ground radar. Not much. The bureau is taking this very seriously. The stunt with the website must have rattled them. It’s not often you get someone capable of doing something like that as well as pulling off a murder. Semi-smart computer types try to hire outside help. They think it’s something you order like an Uber. That’s why they get caught.
    Most killers have a below-average IQ. Even serial killers. Movies like to make them out to be cunning masterminds, but most of them would fail a fifth-grade math test. They fit into the category of disorganized killers. They don’t set out to kill their victims, they just end up murdering them out of some violent impulse. It could be motivated by shame in the middle of a sexual act. A feeling of insecurity. Violence is a way for them to try to assert control. It’s usually messy and unplanned.
    The rarer kind, the organized killers, are the ones who tend to be smarter than the average person. The Unabomber is a textbook example of that. His targets were chosen well in advance and his method, a bomb, was designed to allow him to murder from far away. Bombers tend to be the highest-IQ killers you come across. It takes intense planning and discipline. Of course that could be self-selecting. The dumb bombers usually only end up killing themselves.
    Less premeditated, but intelligent and opportunist, are killers like John Wayne Gacy and Ted Bundy, who were almost in plain sight. They knew enough to stay ahead of suspicion. And when it fell on them, they were so much cleverer than the average killer, the usual rules didn’t apply to catching them.
    Understanding the difference between criminal minds is at the core of FBI behavioral analysis. But being able to describe someone isn’t the same as being able to catch them or really understand them.
    A criminology professor once shared with us a disturbing statistic. He plotted out the average IQ scores of various professions. He drew a circle around law enforcement: 104. Above average, but not by much. He then explained the amount of deviation from this number was very small and the chances of someone with an IQ in the 150 or genius range working in this field are almost infinitesimal.
    If you throw five hundred law enforcement officers after one highly organized killer, statistically speaking not one of them is going to be as smart as him. When you’re dealing with someone like the Unabomber, not one in ten thousand.
    The key, he reminded us, wasn’t being smarter. It’s being persistent. It was logic. Smarter isn’t always an advantage. You could beat a Doberman in a battle of wits on Jeopardy! , but not if you’re locked in a room with one.
    Generally, you catch the less intelligent, disorganized killers because they screw up and get caught with a body in the trunk or their intended victim manages to escape. They leave lots of forensic evidence that makes it easy to connect them
