It could be that Devlin dropped Shawn off and went cruising around the area while Shawn visited with Devlin and that is when he spotted Ben.
The info I got came from KTVI 9pm news. I have to replay it again to find all the details exactly. That will be later tonight and after the 10pm news
correction
Shawn visited with TONY (not Devlin)
that is exactly what happend. While he let Shawn hang out with his best friend he went driving around and spotted a kid that he just had to have.
Anxiously awaiting your report.
