What are you armed with? >> Weapon wise. >> So where's Ronnie Jr. at? Is he inside? Oh. Oh. Oh. What? Where's Junior? Ronnie Junior. Right here. >> What is that? >> Those are ears. Investigators later confirmed the man had killed his grandfather earlier that day, leading to over 50 years behind bars.
