SYOSSET - Nearly four years after four brothers found their parents shot to death in their Syosset home, the boys say they are still searching for whoever killed their mother and father.

Ankur and Josh Singh told News 12 Long Island that they had just come home from school when they found their parents murdered.  They say after that day, life was never the same.

The Singh brothers say police don't know if their parents knew their killer or not, but that it appears there was no forced entry. They also say the investigation was hindered because no one saw or heard anything suspicious.

Ankur Singh says not only is it important to his family to find out who did it, but also why it happened.
