Colton Ferguson, 21, was on trial for first-degree murder in the death of Heather Thurier, 23.

Ferguson shot Thurier at point blank range with a sawed-off .22 rifle after an exchange of words on May 21, 2010, killing her instantly.

There is no doubt Ferguson killed Heather Thurrier, Justice Sterling Sanderman ruled in his decision Thursday.

The question, he said, is whether Ferguson is guilty of murder or manslaughter.

Sanderman concluded the discharge of gun was not accidental and the video shows Thurrier never touched the gun that killed her, Sanderman said, dismissing the possibility of a manslaughter conviction.

Sanderman based his decision largely on the video evidence, calling much of eyewitness testimony flawed, he said.

He also called Ferguson's testimony evasive saying, "'candid' is not a word that springs to mind when describing his evidence."

A sentencing hearing is set for Friday, Mar. 16.
