British man accused of killing wife
The Royal Grenada Police Force said 32-year-old Alexander Clack was in custody on a charge of non-capital murder, meaning the death penalty cannot be considered if there is a conviction.
A post-mortem conducted on Sunday on the body of Nixiann Downes-Clack revealed she died of blunt force trauma and asphyxiation by strangulation.
Her body was recovered on Friday, days after she was reported missing by relatives on the island.
The 27-year-old woman was "suspected to have been the victim of domestic abuse and gender violence," said Delma Thomas, Grenada's minister of social development, housing and gender affairs.
Police said Clack led investigators to his wife's remains in Mt Moritz, a village just north of the capital, St George's.
A teenage girl detained with Clack on Friday has since been released from police custody. The couple apparently had a two-year-old daughter.
He is the owner of SGU Fish Market, a company that delivers fish to hoteliers, supermarkets and retailers.
