Dr Catherine Mullany and her husband were attacked in Antigua
The two GP trainers at the Tabernacle Street Surgery in Skewen, South Wales, were said to have been shocked by the news and have yet to comment further.
The surgery is just a few miles from Pontardawe, where Dr Catherine Mullany, 31, and her physiotherapist husband lived.
The couple were attacked in their cottage while on honeymoon on 27 July, the day before they were due to fly home.
Dr Mullany was found dead at the scene and her husband Ben was rushed to hospital with a bullet lodged in his brain.
He was then flown home to Wales in an air ambulance for specialist treatment but died in hospital after his life support was switched off.
A £67,000 reward has reportedly been offered for information leading to the arrest of the attackers.
Dr Mullany, previously Dr Bowen, had been with the Abertawe Bro Morgannwg University Trust for four years working in cardiology, chest medicine, neurology, nephrology and A&E departments as part of her training for general practice.
Chief executive of Abertawe Bro Morgannwg University Trust, Paul Williams, described Dr Mullany as a 'popular, talented and caring young doctor, with a wonderful career ahead of her.'
'Staff at the trust are shocked and devastated by Catherine's tragic death,' he said.
'The circumstances of her death are particularly poignant as she was on her honeymoon when this awful shooting occurred.'
Dr Tony Calland, BMA Wales chairman, also offered his support and said: 'We were deeply saddened to learn of Dr Mullany's untimely death whilst on her honeymoon and we extend our deepest sympathy and condolences to her family, friends and colleagues who are left behind to grieve.
'To be killed whilst on honeymoon - at the start of married life - is appalling, shocking and tragic.'
Dr Mullany trained at Imperial College School of Medicine in London, and qualified as a doctor in 2002.
