Lucy Quirina de Berk insisted she was innocent at her trial in The Hague for the deaths of thirteen people.  The forty-one-year-old nurse was charged with eighteen counts of murder and attempted murder at four different hospitals, and was suspected in as many as thirty cases.  She was also suspected in several thefts, from stealing drugs to petty thefts of money and books about serial killers.  Her victims ranged in age from a six-month-old infant to a 91-year-old man, and the list of her suspected poisons was long.  While De Berk claimed that her love for life is too vast to end anyone's, she had a history of depression and suicide attempts, and had even once advertised her own death in the papers.  Prosecutors described the former prostitute as sociopathic.  They accused her of killing patients over a period of four and a half years with lethal overdoses of medication.  She had lied under oath about her credentials, which she admitted, had falsified her school diploma, and had stolen copies of patient records.  She was also suspected of being a drug addict.  Her own brother testified against her, saying she was a good liar who was capable of killing and who had shown an unhealthy attachment to terminally ill patients.  Like Genene Jones, de Berk liked carrying dead children and preparing corpses, and after a death would draw a lot of attention to herself.  She kept diaries about her behavior and even questioned in writing whether she was a sociopath.  While she was being interrogated, she actually flirted with male detectives.  In March 2003, de Burk was convicted of the murders of three elderly women and a child and given a sentence of life in prison.  Her case is currently under appeal.
