Here's a unique way to solve a cold case. In 1980, a 14-year-old named Bill Comeans was found murdered near his home outside Columbus, Ohio. The crime has remained unsolved for the last 34 years.

In an effort to bring attention to the case, Comeans’s little sister Kathleen launched a @BillComeans Twitter account, and began tweeting in her brother’s voice.

The tweets include pleas to the public and investigators, newspaper clippings about the case, and a chilling messages to her brother’s killer.

34 years ago today, I was murdered. I was 14 and had my entire life to live. My family is still looking for my killer.

My last meal was a half a bowl of ice cream. I put it in the freezer so I could go get my sis. That bowl stayed in our freezer three years.
