The family of a Glasgow woman who has been missing for two months have made an appeal for information.
Julie Reilly, 47, was last seen on CCTV at 17:00 on 6 February in an Aldi in the Govan area of Glasgow.
She was reported missing on 15 February - her grandson's first birthday - but extensive searches have failed to find any trace of her.
Her mother Margaret Hanlon, 69, and sister Lynne Bryce, 36, have urged Ms Reilly to contact them.
Speaking at a media conference on Friday morning, Mrs Hanlon said: "Please, please if you are out there somewhere, Julie, please let us know you are ok.
"We are all so sick with worry for your safety. We love you so much, hen, and need you back here at home safe with us."
"If anybody anywhere knows of Julie's whereabouts please don't let us go on like this.
"I'm begging you from the bottom of my heart."
Her mother continued: "Julie never misses appointments. This is not Julie. She would be with us now if she was able.
"Any friends, anywhere, even if we don't know you, please if you know anything, no matter how small, please get in touch with the police.
"It could help a lot and bring Julie back to us."
Ms Reilly, who was a frequent user of local public transport, was last seen in an Aldi store on Paisley Road West.
Det Ch Insp Mark Bell said officers were still assessing whether there has been activity on her bank account or mobile phone since then.
He stressed it was a missing persons investigation but added: "I cannot exclude that something sinister has happened to her.
"But it is my absolute wish and sincere hope that I find Julie alive and well."
A forensic search is ongoing at Ms Reilly's house in Shieldhall Road, Govan.
Mr Bell said: "I have to satisfy myself that nothing untoward has happened in that home address."
The search for Ms Reilly is currently focused in Shieldhall, Cardonald, Govan, Penilee and Glasgow city centre.
She has lived in the city for a number of years but her family is originally from Auchinleck, East Ayrshire.
Mr Bell said: "Julie has never been missing before.
"For me, at this time, I don't see an obvious trigger as to why Julie would go missing.
"That is what forms some of my concerns."
The detective declined to comment on Ms Reilly's employment or relationship status or reports she had suffered a brain injury before she vanished.
But he added: "There are elements of her private life that give me areas of concern."
On Thursday, detectives boarded buses and spoke to passengers and handed out leaflets, hoping to jog someone's memory.
Officers spoke to 216 people and it described some pieces of information as "potential positives".
The force has employed its underwater unit, dog branch and specialist search officers as part of their investigation.
Ms Reilly has been known to use the surnames Hanlon, Martin and Collins, is white, about 5ft, of medium with short hair that had been dyed blonde.
When last seen she was wearing a dark blue or black jacket, dark jeans and dark coloured trainers with a white trim on the sole.
