Rocklin Still Murder Free Since 2007 After D.A. Doesn't File Charges Against Teen

ROCKLIN (CBS13) — A Rocklin teen who stabbed a friend's father to death won't be facing any charges after the Placer County District Attorney's office closed the investigation.

Zachary Kachmar, 19, will not be charged in the death of his friend's father, 51-year-old Robert Vickney.

The district attorney's office says after its investigation that an intoxicated Vickney was the aggressor. They say Vickney was angry that Kachmar had broken one of his shot glass.

During the attack, Kachmar happened to have a pocket knife to open a beer. That knife would puncture Vickney's chest.

They say during the attack, the 230-pound Vickney was choking the 130-pound Kachmar until he nearly lost consciousness.

The district attorney's office released a statement that read in part, "The death of Robert Vickney was truly an unnecessary and unavoidable tragedy. His death was a result of the irresponsible consumption of alcohol combined with a volatile temper and the complete absence of a sober or mature influence to control an escalating situation."
