The family of Sonia Blount has urged social media users to be cautious and aware online, saying Ms Blount had paid for an error of judgment with her life.
The warning followed the jailing for life of the man who murdered her after using a fake Facebook profile to lure her to a Dublin hotel room.
Family friend Liz Gaffney spoke outside court following Eric Locke's sentencing.
She thanked the legal team for its hard work, the gardaí for their diligence and meticulous work, Ms Blount's friends and her colleagues at Henkel Locktite for all their support.
“A special word of warning to everybody using social media sites. We urge you to please be cautious and be aware,” she said.
“It is so easy to set up false profiles. Sonia made an error of judgment and paid for this with her life.”
She thanked Justice Michael Moriarty and the jury for its "unanimous, timely decision and for seeing her murderer for the lying, manipulative person he is".
“For this, our family is so grateful,” she said.
She noted however, that the verdict would never bring Ms Blount back.
“Sonia was an innocent, beautiful, kind, caring person and a mother, who is sadly missed by all of us who knew her and loved her,” she said.
Detective Superintendent Brian Sutton spoke on behalf of An Garda Siochana.
“Our thoughts and our prayers are with the family of Sonia Blount today,” he said.
“It was a difficult investigation, and I hope the outcome of the court case has brought some bit of closure in relation to the tragic circumstance and event that they’ve been through.”
He said the force was pleased with the investigation.
“A lot of work went into it,” he said.
He thanked the witnesses, who came forward, the staff in the Plaza Hotel, and the family who he said had given a good background and assisted them with the result.
