God it's horrible trying to imagine how this argument escalated
into criminal tragedy.
Police say Ketunuti had called an exterminator service that day because of rodents in her home, and Smith - a subcontractor - was dispatched.
Once in the home, police said, there was some kind of argument in the basement. The argument escalated, police said, and Smith allegedly knocked Ketunuti down, got on top of her and strangled her.
Police believe Smith then set her body on fire in an attempt to hide the evidence.
