As referred in Oskar's family bio, her death left her husband distraught and he thought he had nothing to live for any more. Thankfully, his best friend came to live with him. Both also died later, yet the two are now playable ghosts, unlike Anna.
Anna, like the other deceased Sims from the neighborhood, has dark skin, yellow eye, and dark clothing with brighter patterns.
Angelika Olsen, a male social worker may be related to her and her husband.
