Viewers to Pick Ending of 'Hawaii Five-0' Episode EW

Viewers will pick the ending of a new episode of "Hawaii Five-0," with CBS saying the twist is the first ever of its kind, reports's Inside TV.

The Jan. 14 episode will allow viewers to vote for the person they want to be the killer of an O'ahu State University professor. The suspects are his boss, teaching assistant and a student who was caught cheating. Viewers will be able to vote via Twitter and on, the story says.

“I’ve always felt the most fun aspect of watching a mystery is trying to figure out whodunit,” said Peter Lenkov, executive producer. “Now the 'Hawaii Five-0' viewers will actually get the chance to tell us who they think committed the crime and we will listen. I love that our dedicated and attentive fans will actually play a part in resolving our story.”
