A couple found dead in their holiday hotel beds with their four-year-old son were poisoned by toxic fumes left behind after the room was fumigated, investigators believe.
The bodies of victims Viviana Andrea Canro Zuluaga, son Kevin and partner Tito Nelson Martinez Hernandez were discovered by her horrified parents on 11th July.
Local media reports say they had been on holiday with the family but were staying in a different room.

But when Viviana, Kevin and Tito had not emerged from their room 48 hours after they checked in, they demanded to be let in.
Earlier, Viviana had been alarmed by the "musty" smell in their fourth-floor room when they checked into the Portobelo Hotel, on San Andres Island, Colombia.
But, it emerged, when she demanded to be moved to another room, staff told her it was impossible.
The family and Viviana's parents had been on a GBP 1,452 break at the beachside hotel when they complained about the state of their room.

Kevin's grandparents had been staying in a different room on the ninth floor, reports local media.
In a series of haunting voicenotes sent to her grown-up daughter Mayerli Andrea, hours before the family died, Viviana's fears for their safety emerged.
One said: "This hotel is really, really, musty. But you could have seen how mouldy it is. It smells so, so bad.
"They don't have toilet paper, they don't have bathrooms, they don't have towels.
"I felt bad for my parents. No, I don't know what to do. Right now, the room is terrible, really."
In another, she added: "I asked a girl: 'Can you change my room?'
"She gave me a rude answer, saying: 'Not today, maybe tomorrow.'"

But by the morning, Vivaiana, Tito and Kevin were dead, reports local media.
Police are now investigating any links between their deaths and a fumigation operation in the room before they checked in.
Pest controllers Livingston & Company had carried out the operation just days before the family, from Bogota, had arrived.
A hotel spokesperson said: "We have requested a detailed report from the company, including technical specifications for the products used, names of the staff involved, and all the circumstances of time, method, and place."
And they admitted: "The couple requested a room change after detecting a strong odour in the room.
"But despite being told, it was not possible to do that because the hotel was full."
Police have sealed off the hotel's fourth floor until they can establish how the family died.
