The body of a woman found dead in Dublin yesterday morning has been named locally as Ballina native Nicola Keane.
A post mortem will be carried out today on the body of the pediatric nurse.
Midwest News understands that Nicola moved from Ballina to live in Dublin more than six years ago with her partner.
Her death and the discovery of the body of a baby boy in Lucan are being treated as a family tragedy.
The woman's body was discovered at Lower Road in Strawberry Beds, after she was seen acting erratically on the M50 Toll Bridge early yesterday morning.
Gardai then found her 7 month old son in an unresponsive condition at a house in Lucan - he was pronounced dead at the scene.
A post-mortem on the infant boy has been completed but the results aren't being released for operational reasons.
Gardai are treating the deaths as a family tragedy and aren't looking for anyone else as part of their investigation.
The family of the mother and child have appealed for privacy.
