A baby found dead alongside his mother at the weekend may have died from an insulin overdose, GardaĆ­ believe.

The bodies of baby Vincent Donohoe (11 months) and his mother Kate (44) were discovered together on a bed in an upstairs bedroom of their home on Saturday.

Emergency services rushed to the house in Clonee, Co Dublin after being contacted by a neighbour.

However, it is believedĀ that the mother and child may have been deceased for up to 48 hours at that stage.

It is understood a detailed note was recovered by GardaĆ­.

This note has led to the tragedy being classified as a criminal investigation but investigators are not looking for anybody else in connection with the deaths.
