The sister of a missing Londonderry man says her family's anguish is "getting worse" every day he's gone.
Father-of-three Stephen McCloskey (33) left his sister's home in Ard Grange in the city on Tuesday, October 28 but has not been seen since.
The alarm was raised when he failed to return to celebrate Halloween with his partner, two sons and daughter.
His family grew increasingly anxious when his Nissan Terrano 4x4 was found abandoned in Burt, across the border in Donegal.
Searches for the missing man continued yesterday with the Garda deploying a helicopter.
Meanwhile, his sister Lisa McCloskey spent the day putting posters up around the surroundings areas in a bid to jog the memory of anyone who may have any information about her brother.
She tearfully told the Belfast Telegraph that every day he remained missing it was getting worse for her family, who are desperate for his safe return.
She said: "We're not good, we are getting worse now as the days go on.
"It's getting worse. It's unbearable what we are going through, we just want him home."
Stephen's partner of 15 years Sinead is expecting the couple's fourth child.
She was recently taken to hospital due to the stress of the situation and was kept in for observation.
Lisa said: "Sinead is (in a) terrible (way).
"The wains are missing their daddy so much and so is Sinead, the whole family are. It's killing us.
"It's so out of character, he dotes on his wains and his girlfriend.
"They've been together for 15 years.
"We are just appealing for anybody to come forward with information, should it be the silliest wee thing or they don't even think that it means anything, even if they think it could help in the slightest wee bit.
"It's just getting worse for us", she added.
Family and friends have joined together along with volunteers from Foyle Search and Rescue to search the fields around Burt - a place that holds no association with Stephen.
Speaking previously, Sinead said: "I need him, the children need him.
"We just want him home; we all miss him.
"If he could only see how many people are out searching for him and how we are all in bits."
Police have appealed for anyone with any information about the whereabouts of Mr McCloskey to contact them immediately on the non-emergency number 101.
He is described as being 6ft tall, of stocky build with short brown hair and blue eyes.
He has names tattooed on his left arm and right wrist, and when he was last seen he was wearing a dark T-shirt and dark jeans and was driving the black Nissan Terrano.
In a statement appealing for information, PSNI Sergeant Joe George said: "I would ask Stephen, or anyone who knows about his whereabouts, to contact Strand Road police station on the non-emergency number 101."
