Ruth Walker is the mother of immature mother Ashlee Walker, whose daughter Sierra died from measles.
History[]
Ruth was a hot headed woman who often fought with Ashlee, which often turned into physical abuse. When she hadn't seen Sierra in two days, she reported this to the Special Victims Unit. When Ashlee pretended she didn't know where her daughter was, Ruth comforted Ashlee but physically assaulted her when she discovered that Ashlee did know.
After discovering that Sierra died from measles caught by Monica Stewart's unvaccinated son, Ruth once again comforted Ashlee and became determined to get justice for Sierra. When Monica was acquitted, Ruth and her family went to Monica's house to harass her. Stabler placed her under arrest but it was unknown whether Ruth served time. (SVU: "Selfish")
