I don't wanna say this but I think she killed them

Olive Specter has a very interesting past!
Here's my theory:

You see, she had her first kiss with Earl E DeMise, then they got engaged, but Earl E left her at the altar! This made Olive furious and she killed him. Not only him, but also his brother. After that event, if you noticed, she falls in love, gets married, and her husband dies. She killed all of her husbands, because she wanted revenge!..

p.s. Have you seen her wardrobe? She has a maid costume, a repairman costume etc. I think she killed them, too.

How creeeeeepy! I never knew this. She's a little odd, isn't she. She wants to see their ghosts, too, so I sit her in a chair in her creeeepy garden and she just waits. They never come, though. You find out some interesting things browsing the memories of Sims!

maybe all of them died of old age

hmmmmm her nephew might be next if she killed em maybe she set fire in their homes?

hmmmmmm her nephew's boyfriend may be next
