Watched the Crime Daily interview with Boyce (thanks, LauraNYC). He mentions DNA on phone but no prints - suggests killer did wear gloves or wiped the phone. I don't buy the phone and earbuds being thrown those distances. Way too far. If he hit her with a rock, which I read somewhere, the cell is going to drop then or when he grabs her. The scattered earbuds, volume control imply the struggle happened there off the path. She's fighting for her life and it's messy. He gains control, kills her, etc, and drags her into the deep weeds to hide the body. He's been bitten, probably on his dominant arm/hand, and is in pain; why did her teeth break biting him - because she bit down to the bone on his arm or hand. If so, he's not going to throw a cell phone 80 feet or so. And it's not going to be with the body then anyway. The perp's not going to throw it 132 feet from the path in the beginning either, as Boyce states, when he's fighting an athletic woman who knows she's going to die. So he goes back to the path and gets it? Then throws it as he's leaving the park? Or he's got it in his pocket and drops it as he's heading out of the park? He's not going back on the path - he's too messed up - so he's staying in the weeds heading toward the exit in that direction. Or he leaves it intentionally a ways from the body so the body will be found quickly but not too quickly? Maybe.
