1. THREE LITTLE WHITE COFFINS

On Friday, April 13, 1973, English drifter David McGreavy found himself babysitting the three young children of friends who’d graciously let him stay at their house. Annoyed by a nine-month-old female baby’s crying, she smashed her skull in with his fists, then strangled the four-year-old boy with a wire and slit the two-year-old girl’s throat. He then impaled the children’s dead bodies on garden railings outside. According to the children’s mother:

I remember the three little white coffins at the funeral and being in the crematorium with my parents but that’s all….He might as well have killed me. I lost my children, my husband, my home, my sanity—everything—because of him.

2. ‘NO ONE WOULD HEAR THEM SCREAM’

Christine Falling was an epileptic and mentally impaired Florida girl who as a child would drop cats from deadly heights to “test their nine lives.” As a teenager she was unable to secure any kind of a meaningful job beyond babysitting and caregiving. She became one of America’s youngest serial killers by fatally suffocating at least three children and causing an elderly man to have a heart attack during her first day on the job with him. When arrested, she confessed to police that she heard voices commanding her to “kill the baby” and that she murdered the children by “smotheration”:

The way I done it, I seen it done on TV shows. I had my own way, though. Simple and easy. No one would hear them scream.

Last year an unnamed British man—who allegedly had previous sexual relations with his twenty-year-old babysitter—acted like it was no big deal that she’d had sex with his eleven-year-old son. Text messages suggest he’d actually encouraged it. The father told the court:

I know he told her he was 15. He looks older than his years. He’s sex-mad. He would’ve been fully up for this experience and in many ways sees it as a notch on his belt and is totally unaffected by it.
