What about dna on the phone & buds?? Are they testing it? Did Keith pick up the phone when he found it? I am guessing he had to, to confirm it was Sherri's. Did he pick it up and throw it back down in place? Sounds very strange to me.
He tracked the phone using an app. The app took him to the location. He probably recognized the phone (and case, if there was one) and earbuds. I doubt he had to pick it up to ID it. How many other lost phones would there be at the location the app led him to? Nothing in the article suggests he picked it up and threw it back down. So, I have a hard time seeing anything strange about it. I guess you'd have to clarify what you mean.
