I'm pretty sure a lot of Maidens died fighting super powerful Grimm or of old age or sickness or what have you. They don't necessarily have to have been murdered by someone in order to die and pass on their power.

Even if they are murdered, if it's a slow enough death, they have time to think of someone other than their attacker if they keep a level head.

That's why I said that Summer could've been killed quickly, with the last thing she saw being her killer's face, thus causing her not to have enough time to think of Ruby.
