The family of a Renfrew man who has been missing in Spain for four months have said they will never give up searching for him until he's "back home where he belongs".

Gary Watson Shearer arrived in the resort of Puerto del Carmen in Lanzarote on March 16, to celebrate St Patrick’s Day.

The 53-year-old was then last seen in the early hours of the next morning, and he then failed to show up for his flight home a week later.

Following his disappearance, Spanish authorities carried out a search of the area in June.

Gary’s sister Debbie Shearer has shared the family’s distress as they continue to look for answers into his disappearance.

Glasgow Times:

She said: "We were notified after the search of Puerto del Carmen that it was unsuccessful and they didn't find anything relating to Gary's disappearance."

Debbie explained that the latest update that they have had is details of where her brother's phone was last pinged. The family also saw CCTV footage of him which showed him lying in a doorway. 

She said: "We will never give up until we have Gary back home where he belongs - as a family that is our main focus."

The Celtic fan reportedly disappeared from outside Bar 67 in Puerto del Carmen, however, the CCTV cameras show he was lying unconscious in a shop doorway next to the pub at around 1.30am on March 17.

Debbie said: "To this day, my questions still haven't been answered and they have now come back to us and said it's the wrong IMEI number they have for Gary's phone.

"They have also now said they don't have any CCTV of how Gary got up off the floor or who supported Gary in getting up from the doorway."

Debbie added that her family have faced a lack of communication from Spanish authorities around the investigation.

She said: “The Spanish police on the island have transferred Gary’s case to the head of police on Gran Canaria and any communication (if any) is done through WhatsApp and we have to prompt them for communication.

“The Spanish police had only done their first search for Gary on June 20, and I believe this was only done because our local MP Gavin Newlands took the case to the House of Commons.”

Approaching the 18th week since he was last seen, Debbie said it has left the family living with “daily torture” not knowing what happened to their loved one.

Debbie said: “We are living with daily torture of not knowing what has happened to Gary.

“We are living our lives in that precise moment, we are all struggling in every way possible – mentally, emotionally, and physically.

"One minute we are angry, crying, exhausted, frustrated but then we think and talk about the memories with Gary."

Gary's loved ones have also previously flown out to the resort to carry out their own search.

He was last seen wearing a Celtic top, shorts, and white Nike trainers with green and yellow flashes.

While he is described as being around 5ft 2inch tall, has short hair, and walks with a distinctive limp.

Gary also has epilepsy and type 2 diabetes.

While questions surrounding Gary's disappearance remain unanswered, Debbie said: "Everyone we know has been fantastic with the support and love they have shown us and Gary.

"Gary is a very loved man and always laughing and joking with everyone. This has left a very big void in our family.

"My mum is finding Gary's disappearance especially hard as she is Gary's carer."

She added: "We know we will never get the answers of what really happened to Garry in the circumstances surrounding his disappearance."

The Guardia Civil has been contacted for comment.
