Mishou Autopsy Results 

Autopsy results show that Blake Mishou of Greenbush was killed by his girlfriend’s former lover from a gunshot wound to the head.

19-year-old Eric Niles of Alton broke into a home in Bradley on Sunday morning, where he found his ex-girlfriend, 18-year-old Kristen Cates, and Mishou staying.

State Police believe Niles went there to confront the couple, and eventually shot Mishou before kidnapping Cates.

Authorities tracked Niles to Connecticut. He shot himself in the head after a high speed chase.

Niles died a short time later.
