FRESNO, Calif. — A Fresno County sheriff’s detective has pleaded not guilty to fatally shooting his colleague in what authorities initially called a tragic and accidental shooting.

The Fresno Bee reports (http://bit.ly/2vmsjQN ) 34-year-old Jared Mullis entered his plea Thursday to a felony charge of involuntary manslaughter in Fresno County Superior Court.

Authorities say Fresno County Sheriff’s Sgt. Rod Lucas died in October while talking with Mullis about how to carry their backup weapons.

In court papers, prosecutors say Mullis killed Lucas without malice, but the killing was unlawful because he failed to use “due caution and circumspection.”

The charge includes a weapons enhancement because Mullis used his firearm, which means he may face a longer sentence if convicted.

Fresno defense attorney Roger Wilson said Mullis is innocent because the shooting was an accident.
