From what I know, Prince Dipendra (of the Shah dynasty) massacred his family just because they wouldn't let him marry Devyani Rana (of the rival Rana dynasty) and then he suicided. You could say it's quite similar to Seung-Hui Cho's suicide attack at Virginia Tech last year, but probably even worse considering it was his own family.
Actually, the situation was far more complicated than that.
It's true that there had always been this huge rivalry between the Shahs and the Ranas, but Prince Dipendra's wish and plan to marry Devyani Rana was mainly opposed by his mother Queen Aishwarya, and it wasn't because Devyani happened to be a member of the Rana clan. In fact, Princess Shruti who was Dipendra's younger sister was married to a wealthy Rana named Gorakh Kumar Rana, and despite the fierce rivalry, inter-clan marriage between the Shahs and Ranas wasn't all that unusual or uncommon. (It's sort of like a Manchester United fan deciding to get together with a Manchester City fan to have a nice cup of tea. Pardon my terrible analogy)
But what made the Queen vehemently oppose the marriage was that she happened to have had a row with Deyani's mother Usha Rana. This happened shortly after discreet enquiries were made about the Prince's marriage plans. Bascially what Devyani's mother said to the Queen was that their family was descended from the Maharajas of Gwalior who were an extremely wealthy and influential Indian princely family implying that the Nepali royal family wasn't good enough for their daughter. This really pissed the Queen off, and basically ruled out her changing her mind about Dipendra's marriage to Devyani. But there were also other reasons for Queen Aishwarya strongly objecting to the marriage which were more speculative in nature such as there had been an impure intercaste marriage in the distant past in Devyani's family, that Devyani's astrological signs didn't match those of Dipendra's, that they weren't of pure Rajput stock....and the list went on and on.
His marriage was also opposed by his sister Princess Shruti, but he was also disappointed with his father King Birendra who even though didn't openly object to his marriage plans, remained indifferent to the situation, and didn't really show any support towards his son nor did he take effective actions to find a resolution. Finally he was becoming jealous of his younger brother Prince Nirajan who had always been the Queen's favourite. All of this compounded by the fact that Dipendra was a heavy drinker, and was high from time to time finally led to the massacre.
