A man has been convicted of the murder of a bread delivery man who was shot four times at close range in a Topaz petrol station in Limerick.

John Coughlan from Pineview Gardens in Moyross has been sentenced to life for killing Daniel Treacy (35) on the morning of February 22nd 2010.

The Central Criminal Court heard he walked into the Topaz shop on the Ennis Road and shot Darren Treacy three times in the head and once in the groin with a glock pistol before driving off.

The 33-year-old's brother Darren was killed in November 2005 when he was beaten up by a number of people including the deceased's brother. The prosecution argued the gun attack on the father of two was revenge.

However the jury heard psychiatric evidence that Coughlan was suffering from paranoid schizophrenia at the time of the killing.

The defence argued he suffered from a mental disorder that substantially diminished his responsibility, making the crime one of manslaughter. The jury has rejected the defence and convicted the electrician of murder.

In a victim impact statement, Daniel Treacy's sister Ashling spoke of the sorrow, grief, heartache and sadness her family wakes up to each day.

Mr. Justice Paul Carney has imposed the mandatory life sentence for murder.
