This is the devastating moment a newlywed TV journalist broke down over the body of her prosecutor husband after he was assassinated while honeymooning on a Colombian beach.

Marcelo Pecci, 45, was shot dead in front of his wife Claudia Aguilera in Isla Barú outside the Caribbean city of Cartagena on Tuesday.

The execution took place moments after Aguilera, who worked for television network Unicanal, and Pecci, who has been waging a war on drug cartels, announced they were expecting a baby.

The high-profile couple, from Paraguay, had just uploaded a photo to Instagram of themselves embracing on the sand behind a pair of baby sneakers.

‘The best wedding gift is… life bringing you closer to the most beautiful testimony of love,’ Aguilera wrote on her account.

Aguilera told Colombian law enforcement investigators that the two suspects approached them on the beach at the Decameron Hotel and did not say a word before one of them shot Pecci, once in the face and once in the back.
