His son(Prince Dipendra) didn't commit suicide. He was also shot during their family gathering on Friday night. He died 2 days later in the hospital. Actually, the investigation said he opened fire and killed his father, mother, brother, sister and his relatives. But nobody in Nepal believes that. His brother Gyanendra wanted to become a king of Nepal so people believe he plotted that mass killing. Gyanendra became 13th king of Nepal. In 2008, Nepal became a federal republic and kicked out the monarchy. They ruled Nepal from 1768-2008.
