Narrowing the list of suspects
In Chapter 1, we found a list of people whose cars matched the description of the one that kidnapped Bayes:
- Fred Frequentist
- Ronald Aylmer Fisher
- Gertrude Cox
- Kirstine Smith
We'd like to narrow this list down, so we obtained credit card records for each suspect. We'd like to know if any of them recently purchased dog treats to use in the kidnapping. If they did, they would have visited 'Pet Paradise'.
The credit records have been loaded into a DataFrame called credit_records.
