I just heard the news about Riley's car. It was vandalized last Saturday. There is no
doubt Jordan did it. I went to the bowling alley that night. I bowled a 160! Anyway, I saw
Jordan there and, although it was barely noticeable, I definitely saw paint on Jordan's
shirt. It is unlikely there would be paint on Jordan's shirt unless Jordan had spray-
painted Riley's car. It is a shame, really, since it was such a nice shirt. It was the green
one. Oh, and you know Jordan has motive. After all, Jordan has a well-known grudge
against Riley. You remember when Riley borrowed Jordan's lawnmower and did not
return it. And there was opportunity, because Jordan does not work on the weekend
and usually stays home watching television. But the lightning storm earlier last week
short-circuited Jordan's TV set. Besides, they canceled Jordan's favorite Saturday
evening show.
