R v Rita, Martin and Ben Jenny, an aspiring ballerina with an upcoming ballet company audition, shares a flat with her sister Rita. Every day Rita tells Jenny she is too heavy to be a ballerina, and puts a lock on the refrigerator door. Jenny soon develops anorexia. As Jenny’s weight plummets, Rita begins praising her daily, telling her she will have a great audition because she is so slender. Within two months, Jenny’s weight has dropped to 70 pounds. The day of the audition, Jenny is so frail she cannot get out of bed. When she tries to stand up Jenny suddenly goes into cardiac arrest, and Rita rushes to call the paramedics. When paramedic Charles arrives at the flat, he sees Jenny convulsing and bleeding from her nose. Realising he hates the sight of blood, Charles panics and administers Jenny a shot of adrenaline to her eye instead of her heart. Within three minutes Jenny is dead. You are a CaseManager for the CPS and are asked to review the case against Rita.
