"Isaura Garcia of Los Angeles said she dialed 911 to report domestic abuse by her partner in February. When police entered her fingerprints in the database linked to ICE, the system determined she was in the U.S. illegally. Though she had no criminal record, she landed in deportation proceedings."
This doesn't make any sense. I have never fingerprinted a witness or an R/P. I am guessing that the R/P was arrested for some type of offense, and then those prints were submitted.
