Oklahoma manager says he tried to stop workplace beheading

A manager at an Oklahoma food processing plant testified Friday that he tried but failed to stop a beheading attack three years ago.

He attempted to stop his co-worker, who had been suspended earlier that day, from attacking another employee with a butcher knife by severing her head.

Gary Hazelrigg told jurors that the victim, Colleen Hufford, was 'completely surprised' when Alton Nolen came up behind her, pulled her head back and drew the knife across her throat.
