ST-CROIX, Que. -- The suspect in a quadruple slaying south of Quebec City earlier this month has died in hospital without ever having spoken to investigators.

Quebec provincial police say Martin Godin died Sunday in the hospital he'd been taken to after a suicide attempt.

Godin was suspected in the murders of his ex-wife, her new boyfriend and his own two daughters.

The deaths occurred in two different towns in the Chaudiere-Appalaches region south of the provincial capital.

Police found Godin's ex-wife, Nancy Samson, 44 and her new partner, Benoit Daigle, 39, outside a home in St-Croix. About 70 kilometres away, they found Godin and his daughters, Beatrice, 11 and Medora, 13, in a home in St-Isidore.

Godin, 54, was taken to hospital on Feb. 1 in critical condition and never regained consciousness. He was never formally charged.

Police initially said the family drama may have been triggered by a love triangle.
