To my surprise, the officer did call me back this morning. He said that he located the owners of the van and THEY have spoken with their 15 year old son. The officer said that he is still going to meet with the 15 year old to have a talk with him. I am satisfied with this plan.
I will train myself to check license plates. This is a good habit to practice. I will also put a pencil and notepad in my under-seat pouch.
Thank you for the encouragement and the suggestions!
