After being found guilty of killing five persons in Devinuawara in 2000, six people received death sentences.
The six accused were found guilty of shooting five persons, and Matara High Court Judge Thamara Thennakoon subsequently ordered their execution.
When a mob in Devinuwara opened fire on their van in 2000, five people were savagely shot to death.
Five of the 15 people who were detained in connection with the killings were later released after being found not guilty.
Four suspects have passed away throughout the 22-year trial.
The murderers were all Devinuwara locals.
