Andrew Robinson, aged in his 50s, was last seen at around 1.10am on Saturday, November 15, in the Portadown area.
His car was later discovered close to the River Bann, triggering an extensive multi-agency search operation.
Today, his wife Elizabeth Ruth Robinson posted a photo of Mr Robinson alongside heart emojis saying: “My darling husband. We finally have you home.”
Community Rescue Service (CRS), K9 Search & Rescue NI, Lough Neagh Rescue, Foyle Search & Rescue, East Coast Divers, Meath River Rescue and members of the public with sonar, including “some from England”, all played their part in extensive search efforts.
CRS said: “Yet more sad news. Over the past six weeks CRS had been deployed on a daily basis to the Portadown area to an ongoing search alongside our NISAR colleagues from Lough Neagh Rescue.
“Searches were also conducted by NISAR colleagues from the Police Service of Northern Ireland, Sky Watch NI, Search & Rescue Dog Association – SARDA Ireland North and Foyle Search and Rescue
“Searches were also conducted by teams from outside NI, local river users and other members of the public.
“We regret to inform you that earlier today a body believed to be that of the missing person, was located by a search team from RoI who travelled north to assist in the ongoing operation.
“The management and volunteers of the Community Rescue Service extend our deepest sympathy to the family and friends of the deceased.”

DUP MP for Upper Bann Carla Lockhart offered her condolences to the family.
She said: “Truly devastating for the Robinson family at this Christmas time. My thoughts and prayers are very much with them.
“They have lived for the last 42 days as a nightmare, and whilst there is a sense of relief they now know, the finality of all of this hits hard.
“I have been liaising with both them and the police on an ongoing basis for the last month.
“Their resilience throughout all of this has been amazing. At least now they can put Andrew to rest.
“I want to thank all those who have helped in any way, especially all the search teams who were relentless in their search of Andrew. There were those who went over and above and the family know who they are loved.
“To Ruth and the boys, and the whole family – you have been a credit to Andrew and never gave up hope. We will be remembering you in the days and weeks ahead.”
Her party colleague Jonathan Buckley also shared the post from Mrs Robinson.
It’s understood that formal identification of the body will take place.
On Christmas Eve K9 Search & Rescue said its volunteers were back in Portadown, continuing searches of the River Bann for Mr Robinson.
“In the stillness of the morning, teams searched on, driven by the hope of bringing some form of answer to those waiting at home,” it posted.
“At a time meant for warmth and reassurance, his family and friends are enduring uncertainty no one should have to face. Our thoughts are firmly with them, today and always.
“We remain committed to supporting the ongoing search efforts in any way we can.”
