Jenny Johnson

Jennifer "Jenny" Johnson (died 2017) was an undercover agents of the International Domain Name Directory (IDND).

Biography
Jenny was approached by Black Siren as she went out of her gym; just before she get in her car the villaness, introducing herself as "Dinah", gave her back the keys she had inadvertently lost. The two women chatted friendly for a few minutes and "Dinah" complimented Jenny for her shoes, then she killed her and stole her fingerprints in order to enter the International Domain Name Directory vault.

Oddly enough, when Team Arrow arrived on the place, Black Siren was still there and she confessed to Black Canary that Jenny was "so pretty that she wanted to hold her hand till the end" and that this made her waste time rather than escape quickly.
