The grieving widow of tragic sewer victim Alan Harris made an emotional tribute to her "soulmate".
Tracy Glynn Harris declared her heart had been broken "into a million pieces".
The father-of-two died when he was killed by toxic fumes while working in a sewer at Drumnigh Wood estate in Portmarnock, Co Dublin on Wednesday.
His younger brother Steve - who tried to rescue him in the sewer - was also overcome by the fumes and is in a critical condition in Beaumont Hospital in Dublin.
Tracy received the devastating news while in Turkey on a brief holiday with female friends. The couple, married 22 years, have two grown-up children, Nicole and Alan junior.
The family have called publicly for prayers for Steve's recovery.
Tracy's heart-rending tribute to Alan on Facebook declared: "Tragically yesterday I lost my best friend and soulmate Alan Harris.
"My heart has been shattered into a million pieces yet again."
She thanked everyone who had offered words of kindness at this devastating time for the family.
And she paid tribute to the heroism of Steve who had desperately tried to save the life of his older brother.
"Please send all your prayers to his brother Steve Harris who is fighting for his life after trying to save Alan's," she declared.
Alan was one of a family of six brothers and one sister who grew up in Monasterboice Road in Crumlin in Dublin.
His heartbroken brother Mark stated that Alan was "a special man".
In a moving tribute on Facebook, he said: "My heart is broken today about the death of one of my wonderful brothers, Alan Harris, a special man who I looked up to. His achievements in life are too numerous to mention. He will always have a special place in my heart."
He, too, called on everyone to pray for "another special person, my baby brother Stephen".
Alan Harris lived in Clonee, and the local soccer club Clonee United paid tribute on social media.
He had played for the club and was a close friend of several club members. The club offered "heartfelt condolences" to his family.
Neighbours of the Harris family in Crumlin told the Herald yesterday the hearts of the entire community went out to them.
"There's no answer to what has happened. They are a really lovely family. It is so sad. It's a terrible tragedy. Alan was a lovely man, like his father. Our hearts go out to his mother Gertie and all the family," said a family friend.
A number of investigations into the tragedy are under way.
Alan Harris (45) ran his own drain and sewer maintenance business.
