Case Studies

The following case studies catalog lives that could have been saved if DNA had been required upon arrest for felony crimes.

Chester Turner — California

Chester Turner was arrested for assault with a deadly weapon in 1987. He was not convicted. In fact, Turner was arrested a total of 21 times before he was ever formally convicted of any crime. In 2002 he was convicted of rape, his DNA was taken, and it was found to match twelve other unsolved rape and murder cases. The first of these victims was raped in March of 1987. DNA taken upon his first felony arrest could quite possibly have saved the next eleven lives. More...

Each victim is a tragic testament to the potential for DNA testing upon arrest, to halt the needless victimization of innocent people!
