Britain's worst serial killer, Harold Shipman, a family doctor, was jailed for life yesterday for murdering 15 women patients with heroin injections.
Police are considering bringing 23 other murder charges and do not rule out the possibility that the doctor killed nearly 200 people in his 20-year career.
Prosecuting lawyers said Shipman had a need for control that fuelled a hunger for "power of life over death".
"The judge has said that the sentence of life imprisonment will mean life," Mr Robert Davies of the Crown Prosecution Service said after Shipman was sentenced to 15 life terms.
