Catherine Shaw: Drones used in missing Briton search
Drones and mapping technology have been used in Guatemala as the search for a 23-year-old British woman continues.
Catherine Shaw, from Witney, Oxfordshire, was reported missing after she left Hotel Mayachik near Lake Atitlan in the early hours of 5 March.
A Facebook appeal page said she left the accommodation with a puppy, which was found at the summit of a nearby mountain that is popular with hikers.
A jacket belonging to Ms Shaw was found at San Juan La Laguna on Monday.
Her parents Ann and Tarquin released a video appeal via the Lucie Blackman Trust, which said she had been in the central American country with a friend.
She has been travelling since September 2018 and had previously been in Mexico and California.
Jess Elizabeth, a friend of Ms Shaw, wrote on Facebook that the 23-year-old had "no belongings with her, passport, money or mobile phone - they were left at the hostel".
People searching for Ms Shaw said she left Hotel Mayachik twice, at 01:37, before returning and then leaving again at 05:23 in the direction of Lake Atitlan.
Over the weekend Guatemalan police, locals and Britons in the country went to the peak of the Indian Nose hiking trail, where the puppy was found.
Two drones were also used to search the wooded area.
On Friday, the Lucie Blackman Trust said Ms Shaw's father was travelling to San Pedro to join the search with volunteers in the area.
Nearly £6,000 has been raised to assist the search effort.
On Sunday, a Foreign Office spokeswoman confirmed it was supporting the family of a British woman and were "in contact with the local authorities as they search for her".
