I'm always looking for new ways to find evidence

In many people's view, I must be braver than the average person. Otherwise, how could I be a policewoman? But they're wrong. The feeling I had when visiting my first crime scene has never faded.

Nearly 30 years ago, about the time I started, a man surrendered himself to my police station, saying he had chopped up his wife after an argument.

I'd imagined many times what a crime scene would be like, but I was still shocked when I opened the door to that man's home. I instantly saw a woman's body on the bed - she had been decapitated.
