When and why were finger prints first used in the united states

He is also credited with the firstfingerprint identification of a greasyfingerprint left on an alcohol bottle. In 1882, Gilbert Thompson of the U. S.

Because of this case where there were 2 guys with very similar names that looked so alike the could be twins. It was very hard for the prison to tell the inmates apart from eachother but fingerprints solved the issue because no fingerprints are identical. I believe it was the "Will and William West" case.
