From the Valley City police log:
A young male called Betty Jensen of Valley City shortly before noon on Tuesday claiming to be her grandson. The caller said he was in jail in another city and needed money.
Jensen told police she kept him on the phone for "quite a while," asking how his trip went, how he wound up in jail and how much money he needed.
After some time, she finally told the caller "There's only one problem, I don't have a grandson." The caller promptly hung up.
