Who is Joe O’Reilly?

Joe O'Reilly, 45, was convicted for the murder of his wife Rachel O'Reilly (previously Callaly) in 2007, after one of the most widely publicised criminal investigations in Ireland.

He killed Rachel with a dumbbell at their home in Naul, Co Dublin on October 4, 2004.

Then, he staged the scene to look like a robbery and led Rachel’s mother, Rose, to find the body. 

Joe also infamously appeared on The Late Late Show with Rose, a few weeks after the murder.

That was the moment where everything changed for Rachel’s mother.

She said that she knew he killed her daughter after the appearance, where he showed no grief for his murdered wife.

Joe was eventually arrested and later found guilty of murder in July 2007.

The jury heard extensive phone evidence which placed him at the crime scene despite his claim that he was working at a depot several miles away.
