ADEL, Iowa (AP) — The adoptive parents of a 16-year-old Iowa girl who weighed only 56 pounds when she died face new charges.

Des Moines television station KCCI reports that 41-year-old Misty Ray and 42-year-old Marc Ray have been charged with ongoing criminal conduct, theft and fraudulent practice. The pair had already pleaded not guilty to first-degree murder, child endangerment resulting in death and other counts related to the starvation death last May of 16-year-old Sabrina Ray.

Misty and Marc Ray face a total of 17 charges in the case. Last month, the teen’s adoptive grandmother, 63-year-old Carla Bousman of Perry, was sentenced to 20 years in prison after admitting to not seeking medical attention for the dying girl and to concealing evidence after Sabrina died.
