It was a royal ceremonial funeral including royal pageantry and Anglican funeral liturgy. A Second Public service was held on Sunday at the demand of the people. The burial occurred privately later the same day. Diana's former husband, sons, mother, siblings, a close friend, and a clergyman were present. Diana's body was clothed in a black long-sleeved dress designed by Catherine Walker, which she had chosen some weeks before. A set of rosary beads was placed in her hands, a gift she had received from Mother Teresa. Her grave is on the grounds of her family estate, Althorp, on a private island.[citation needed]

Document 9: Kanye West: West's life took a different direction when his mother, Donda West, died of complications from cosmetic surgery involving abdominoplasty and breast reduction in November 2007. Months later, West and fiancée Alexis Phifer ended their engagement and their long-term intermittent relationship, which had begun in 2002. The events profoundly affected West, who set off for his 2008 Glow in the Dark Tour shortly thereafter. Purportedly because his emotions could not be conveyed through rapping, West decided to sing using the voice audio processor Auto-Tune, which would become a central part of his next effort. West had previously experimented with the technology on his debut album The College Dropout for the background vocals of "Jesus Walks" and "Never Let Me Down." Recorded mostly in Honolulu, Hawaii in three weeks, West announced his fourth album, 808s & Heartbreak, at the 2008 MTV Video Music Awards, where he performed its lead single, "Love Lockdown". Music audiences were taken aback by the uncharacteristic production style and the presence of Auto-Tune, which typified the pre-release response to the record.
Document 10: Kanye West: In September 2013, West was widely rebuked by human rights groups for performing in Kazakhstan at the wedding of authoritarian President Nursultan Nazarbayev's grandson. He traveled to Kazakhstan, which has one of the poorest human rights records in the world, as a personal guest of Nazarbayev. Other notable Western performers, including Sting, have previously cancelled performances in the country over human rights concerns. West was reportedly paid US$3 million for his performance. West had previously participated in cultural boycotts, joining Shakira and Rage Against The Machine in refusing to perform in Arizona after the 2010 implementation of stop and search laws directed against potential illegal aliens.

Document 13: Seattle SuperSonics relocation to Oklahoma City: The Seattle SuperSonics, a professional basketball team in the NBA, relocated from Seattle, Washington to Oklahoma City, Oklahoma in 2008. The third NBA franchise to relocate in the 2000s, the team began play as the Oklahoma City Thunder in the 2008 -- 09 basketball season.
Document 14: Kanye West: On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.
Document 15: Kanye West: Adams sent condolences to Donda West's family but declined to publicly discuss the procedure, citing confidentiality. West’s family, through celebrity attorney Ed McPherson, filed complaints with the Medical Board against Adams and Aboolian for violating patient confidentiality following her death. Adams had previously been under scrutiny by the medical board. He appeared on Larry King Live on November 20, 2007, but left before speaking. Two days later, he appeared again, with his attorney, stating he was there to "defend himself". He said that the recently released autopsy results "spoke for themselves". The final coroner's report January 10, 2008, concluded that Donda West died of "coronary artery disease and multiple post-operative factors due to or as a consequence of liposuction and mammoplasty".
