A former TV reporter who left KOIN (6) three years ago because of a theft conviction pleaded guilty Wednesday to stealing more merchandise.

Joel Iwanaga, 48, was sentenced to 18 months probation for stealing at least $100 worth of merchandise on June 3 from the QFC grocery store on NW Bethany Boulevard, according to court documents.

Iwanaga was a reporter with KOIN (6) News from 2001 until June 2015, but he resigned after pleading guilty to second-degree theft, a misdemeanor, in March 2015.

The first theft involved about $200 worth of food items and some hats stolen from a Tanasbourne Whole Foods Market, police said in December 2014.

At the time, Iwanaga told police he made a "big mistake" and that there was "no excuse for his actions.
