Background: Harold Frederick Shipman (14 January 1946 - 13 January 2004) was a British general practitioner and one of the most prolific serial killers in recorded history. On 31 January 2000, a jury found Shipman guilty of fifteen murders for killing patients under his care. He was sentenced to life imprisonment with the recommendation that he never be released. The Shipman Inquiry, a two-year-long investigation of all deaths certified by Shipman, which was chaired by Dame Janet Smith, examined Shipman's crimes.
Context: In March 1998, Linda Reynolds of the Donneybrook Surgery in Hyde, prompted by Deborah Massey from Frank Massey and Son's funeral parlour, expressed concerns to John Pollard, the coroner for the South Manchester District, about the high death rate among Shipman's patients. In particular, she was concerned about the large number of cremation forms for elderly women that he had needed countersigned. The matter was brought to the attention of the police, who were unable to find sufficient evidence to bring charges; the Shipman Inquiry later blamed the police for assigning inexperienced officers to the case. Between 17 April 1998, when the police abandoned the investigation, and Shipman's eventual arrest, he killed three more people. His last victim was Kathleen Grundy, who was found dead at her home on 24 June 1998. Shipman was the last person to see her alive and later signed her death certificate, recording "old age" as the cause of death.  In August 1998, taxi driver John Shaw, from Hyde, contacted the police, informing them that he suspected Shipman of murdering 21 of his patients. Grundy's daughter, lawyer Angela Woodruff, became concerned when solicitor Brian Burgess informed her that a will had been made, apparently by her mother. There were doubts about its authenticity. The will excluded her and her children, but left PS386,000 to Shipman. Burgess told Woodruff to report it, and she went to the police, who began an investigation. Grundy's body was exhumed and when examined, was found to contain traces of diamorphine, often used for pain control in terminal cancer patients. Shipman claimed that she was an addict and showed them comments in his computerised medical journal, but a program on his computer showed they were written after her death. Shipman was arrested on 7 September 1998, and was found to own a typewriter of the kind used to make the forged will.  The police then investigated other deaths Shipman had certified, and created a list of 15 specimen cases to investigate. They discovered a pattern of his administering lethal doses of diamorphine, signing patients' death certificates, and then falsifying medical records to indicate that they had been in poor health.  Prescription For Murder, a 2000 book by journalists Brian Whittle and Jean Ritchie, advanced two theories on Shipman's motive for forging the will: that he wanted to be caught because his life was out of control, or that he planned to retire at age 55 and leave the UK.  In 2003, David Spiegelhalter et al. suggested that "statistical monitoring could have led to an alarm being raised at the end of 1996, when there were 67 excess deaths in females aged over 65 years, compared with 119 by 1998."
Question: how did they die?
Answer: his administering lethal doses of diamorphine,

Background: The Cardigans are a Swedish rock band formed in Jonkoping, Sweden, in 1992, by guitarist Peter Svensson, bassist Magnus Sveningsson, drummer Bengt Lagerberg, keyboardist Lars-Olof Johansson and lead singer Nina Persson, with the line-up remaining unchanged to this day. Their debut album Emmerdale (1994) gave them a solid base in their home country and enjoyed some success abroad, especially in Japan. It was not until their second album Life (1995) that an international reputation was secured. Their popularity rose when their single "Lovefool", from the album First Band on the Moon (1996), was included in the soundtrack to the 1996 film Romeo + Juliet.
Context: The Cardigans returned in 2002 to record Long Gone Before Daylight (2003), a collection of songs mainly written by Persson and Svensson. Long Gone Before Daylight became one of the best selling albums in Sweden in 2003. After a two-year hiatus from their last album, it was released in Japan on March 19, 2003 and in Europe on March 24, 2003. Later it was also released in Canada (April 22, 2003) and the United States (May 25, 2004).  The album differs from the band's earlier works. Their familiar "happy" pop sound takes on a change to pop songs with more of an American country music influence. It is a much darker album than their previous works, and quieter than Gran Turismo. Indeed, even lead singer Nina Persson dyed her once light blonde hair to jet black, reflecting the band's change of mood. The album was produced by Per Sunding after the group's regular producer Tore Johanssen stepped down, feeling himself unable to provide the country sound the group wanted.  Criticism was generally mixed to positive. Some found the change of direction welcome, and felt the band had matured, making songs that were even better than other experienced country-pop styled artists. Others missed the old pop sound, and accused the band of possibly being ashamed of their former "happy" pop sound. The first single of the album, "For What It's Worth" was released on February 17, 2003. The second single was "You're the Storm" released on June 2, 2003. The third and final single was "Live and Learn" released on December 3, 2003. In the summer of 2004, The Cardigans toured with Liz Phair, Katy Rose and Charlotte Martin on the Chicks With Attitude tour.  On 28 April 2005 the band's iTunes Originals album was released through iTunes. On 19 October 2005 the band released their sixth album Super Extra Gravity to generally favourable reviews. Super Extra Gravity went straight to the #1 spot on the Swedish album chart and was certified gold (sales over 40,000). After the band finished promotional activities in fall 2006, the band entered an extended hiatus and devoted themselves to other projects.
