The daughters of three elderly victims of the alleged serial murderer are suing the Dallas senior living facility where their horrific killings took place. Diana Tannery, MJ Jennings and Sherill Kerr became suspicious when they noticed valuables were missing after their elderly mothers, who lived on the same floor, died within weeks of each other.
