The young son of tragic Captain Dara Fitzpatrick paid a heartbreaking tribute to his mum on Mother's Day.
The three-year-old released a balloon for his mum to "catch in the sky", according to Cpt Fizpatrick's sister Niamh.
As is Mother's Day we gave Fionn a balloon to release for his Mama to catch in the sky. It just about broke my own mother's heart #Rescue116— Niamh Fitzpatrick (@NFitzPsychology) March 26, 2017
"As is Mother's Day we gave Fionn a balloon to release for his Mama to catch in the sky. It just about broke my own mother's heart," Niamh Fitzpatrick wrote on Twitter.
She also asked the public to continue praying for the recovery of the missing crew members of Rescue 116, Ciarán Smith and Paul Ormsby, and for all the crew member's families.
Search teams have been examining underneath the wreckage of the Rescue 116 helicopter in the hope of recovering the two missing Irish Coast Guard members.
Winch operator Ciaran Smith (38) and winch man Paul Ormsby (53) have still not been found after their Sikorsky S-92 helicopter collided with Blackrock Island off the Co Mayo coast in the early hours of March 14.
Their colleague Captain Mark Duffy (51) was brought to shore on Sunday afternoon after Naval Service divers recovered his body from the cockpit of the helicopter wreckage.
