Yessenia went missing along with her two children (Thalia and Michael Otto). The three of them were all murdered by Luis Toledo (Yessenia's husband and the step-father to Michael and Thalia). Toledo is currently serving life in prison for all three of their murders; however, he refuses to tell anyone where he left the three bodies. All three victims were last seen on October 22, 2013, at approximately 8pm when they left the home of Yessenia's mother (Michael and Thalia's grandmother). (Information retrieved from NamUs.gov)
