DNA analysis has proved body parts found in the Grand Canal earlier this week belong to the torso that of Kenneth O'Brien.

A passer-by spotted his remains floating in a suitcase in the water at Ardclough in Kildare on Sunday afternoon.

More body parts were since uncovered in the canal at Sallins by the Garda UnderWater Unit.

Detectives revealed yesterday that pinpointing the location where 33-year-old Mr O'Brien was killed could hold the key to solving his death.

They are appealing for property owners to check for signs of disturbance on their premises to find a possible murder site.

Gardaí earlier recovered equipment which may have been used to dismember the body of murder victim Kenneth O Brien.
