Who forged the check?
Evidence (7)
#1Handwriting analysis shows the forged signature was written by a left-handed person.
#2Ingrid and Wei are left-handed. Paul, Sandra, and Carl are right-handed.

#4The check was printed on Mr. Harmon's personal check printer, which is kept in his locked office.
#5Ingrid has a spare key to Mr. Harmon's office.
#6Carl has significant personal debt, but he's right-handed and doesn't have office access.
#7Ingrid's fingerprints were found on the check printer, though she says she 'cleans it occasionally.'
