Answer 1

"He [Birendra Bir Bikram Shah Dev] and most of his family (including Queen Aiswarya) were killed under suspicious circumstances, purportedly by his eldest son and heir, Dipendra"

"Dipendra Bir Bikram Shah Dev of Nepal (June 27, 1971 – June 4, 2001) was King of Nepal from June 1 to June 4, 2001. He was accused of slaughtering his family at a royal dinner on June 1, 2001. Dipendra was also mortally wounded, either by his own hand or at the hands of the palace guard, and officially became king for the three days he lingered in a coma."
