Irish TV producer Eamonn Lillis has been jailed for seven years for killing his advertising executive wife Celine Cawley.
The 52-year-old was found guilty last week of the businesswoman's manslaughter after a jury found the State failed to prove intent to murder.
Ms Cawley, a successful ad producer, died after being attacked at the back of the couple's luxury home in Howth, north Dublin in December 2008.
Mr Justice Barry White said while Lillis at least had the decency to call emergency services and attempt to resuscitate his wife, he then persisted to lie to gardai to conceal his own involvement.
"Your behaviour has had a devastating effect on people of all ages," the judge said.
"From your father-in-law, who is some 80 years of age, down to your own daughter, who is 17 years of age."
The judge at the Central Criminal Court in Dublin said the teenager had described in her victim impact statement how she had changed from a 15-year-old girl into a hardened 17-year-old adult.
Members of the Cawley family, including Ms Cawley's father James, sister Suzanna and brother Chris, maintained a dignified silence as the sentence was imposed.
With his head held high as he stood and listened to the judge, a weary looking Lillis did not flinch as he was then led away to Dublin's Wheatfield Prison.
