According to an article in the 30 July 2001 New Yorker and other published reports, the refusal of Dipendra's parents to consent to this marriage was the cause of the massacre of the royal family in Nepal. However a 2009 report based on an interview with his cousin Paras Shah suggested that there may have been other reasons as well. A book "Maile Dekheko Darbar" by former Secretary to the King Birendra suggests that Dipendra may have had significant personality problems.
