I don't recall being able to determine whether someone is possessed or not by a handshake. So, as it relates to your situation, I doubt there was anything suspicious going on.
There are those secret clubhouse handshakes that can get mormons into heaven (linked above), but I don't know of any instance, other than in the temple, that those would ever be used.
And... Smith taught about discerning the status of "angels," whether or not it's a good spirit or a bad spirit. It can be found here:
