Pregnant woman accused of killing 18-year-old, wrapping body in plastic

PHOENIX (KSAZ) - A second person has been charged in the gruesome death of an 18-year-old girl whose body was found covered in plastic wrap in a dumpster earlier this summer.

According to court documents, Stephanie Maria Ritter, who is pregnant, admitted to killing the girl after she refused to leave Ritter's apartment in June.

Ritter told police she smothered the girl, who was a runaway from California, with a pillow while her sister held the girl's legs. Ritter says they also disposed of the body.

Ritter's sister, Lorenda Ritter, was arrested last month.
