Jon thought about the most likely place Karyn could have gone to, then headed off to Athena DeVries' house. Athena was Zoe's best friend. He knew where she lived because he had to pick up Zoe from there a few times. It seemed like the best place to start looking for Karyn.
From where he was, the trip didn't take too long, only a few minutes.
As he walked up to the house, he checked his watch - 5:10 PM. He was losing time. Hopefully, this would all pan out.
He rang the doorbell, then waited.
