The inquest into the suspected murder-suicide deaths of a father and his two sons in Cork takes place later.

All three died of gunshot wounds in Kanturk last October.

This inquest gets under way in Mallow Courthouse, and will focus on the deaths of all three family members.

25-year-old Mark O'Sullivan was shot by his father 59-year-old Tadgh, and young brother 23-year-old Diarmuid, on October 26th of last year.

It happened in the bedroom of their family home in Assolas near Kanturk.

Tadgh and Diarmuid were found dead later that morning close to the farmhouse.

Anne O'Sullivan (61), the mother of the household, was the only survivor of the tragedy.

She was diagnosed with a terminal illness before the shooting took place.

But she died of cancer in April, and the murder-suicide is believed to have been sparked by a dispute over her will.

The inquest is likely to take several hours but is expected to finish today.
