On June 1, 2001 (April 10 of the 2001 lunar calendar), King Birendra of Nepal passed away. The Advisory Council of the Royal Palace of Nepal announced on June 2, 2001 that in view of the sudden death of former Nepal King Birendra at the Narayanhiti Palace on the evening of the 1st, Crown Prince Dipendra will succeed as King of Nepal. As Dipendra was being rescued in the hospital due to serious injuries, Birendra's younger brother, the second king, Jarendra, was appointed as the regent. According to local news media reports, King Birendra and Queen Aishwarya, as well as more than 10 members of the royal family, were shot and killed by Crown Prince Dipendra at the Narayanhiti Palace on the evening of the 1st. The reason was that the Crown Prince and other members of the royal family had serious differences on the choice of the princess. Dipendra later shot and attempted to commit suicide. At 4 p.m. local time on the 2nd, the remains of King Birendra and Queen, as well as the little prince, were transported to the crematorium for incineration. The Investigation Committee on the Incident at the Royal Palace of Nepal announced on the evening of the 14th that the shooting incident at the Narayanhiti Royal Palace on the evening of June 1 was entirely caused by former Crown Prince Dipendra alone. Talanat Ranabat, head of the investigation committee and Speaker of the House of Commons of Nepal, said at a press conference that the direct perpetrator of the accident was former Crown Prince Dipendra, and the main reason was that he drank too much whiskey that night. Ranabat said that according to a comprehensive investigation into the incident conducted by the Supreme Investigation Committee composed of Chief Justice of the Supreme Court of Nepal Keshav Upadya and him for more than a week, and verification by forensic doctors and relevant experts, the shooting was indeed committed by Dipendra. He said that over the past week, the investigation committee conducted detailed investigation and verification of the palace scene where the incident occurred, witnesses, relevant medical staff and the guns and bullets used to create the bloodshed, and finally confirmed that it was a man-made accident caused by former Crown Prince Dipendra. In the shooting incident at the Narayanhiti Palace on the evening of June 1, 10 members of the royal family including King Birendra, Queen Aishwarya, Little Prince Nirajan, and Princess Shruti were killed, and 24 others were injured.
