Samoan opposition member of parliament, Papalii Li'o Ta'eu Masipa'u, is calling on the government to consider an increase of the non-parole period for murder convicts.
An increased number of alleged murder cases has prompted the calls.
Papalii, who is also a lawyer and former assistant police commissioner, says the abolishing of the death penalty some years ago may be another contributing factor.
He says the period should be 20 to 30 years.
Papalii says if he is re-elected in next year's general election it will be one of his high-priority proposals to the new Parliament.
