A former care home manager will be sentenced for killing an elderly resident after stealing drugs from patients to feed her own addiction.
Registered nurse Rachel Baker, 44, gave Lucy Cox, 97, lethal doses of medication while she herself was abusing controlled drugs stolen from Parkfields Residential Care Home, in Butleigh, Somerset.
Baker, of Boundary Way, Glastonbury, was convicted of the manslaughter of Mrs Cox but acquitted by a jury at Bristol Crown Court of the manslaughter of another resident, Frances Hay, 85.
She admitted 10 counts of possessing class A and C drugs, and one of perverting the course of justice.
She denied killing the two women and was acquitted earlier this year of charges that she murdered both of them.
Opening the case in January, prosecutor David Fisher said: "Rachel Baker was, by her own admission, regularly taking prescribed drugs, which must have had a substantial effect on her character and conduct.
"She, for a variety of bizarre and perverted reasons, may have had a desire to control the terminal destiny of some of her residents."
Care assistant Kathy Slade, who worked with Baker, gave evidence, saying she overheard her boss ask Mrs Hay if she wanted to "end it all" two days before she died.
In her evidence, Baker blamed the "stress, pain and emotional turmoil" of running the home for her decision to steal the medication. She also claimed she was left feeling "useless" after the death of one of the home's residents, Fred Green, but she denied that her "diverting" of residents' drugs ever affected their care.
After her conviction in April Mr Justice Royce told her a custodial sentence was "inevitable".
