A 30-year-old mum of three died in agony after she was doused with petrol and set on fire by jealous relatives in a bitter row about a family home.

Victim Margarita Cecena was burned alive in front of her horrified mother and one of her children on 1st July, say police in Mexico.

She suffered second and third-degree burns to more than 70 per cent of her body and had to be intubated by medics so she could breathe.

But after 24 days of agony, she died at a hospital in Mexico City on Sunday, 24th July.

She had suffered three heart attacks and a bacterial infection that spread throughout her body and ended up causing her death.

The State Attorney General’s Office opened a file for the crime of injury after the attack, but it will now be reclassified as femicide.

The investigation is ongoing and, at the time of reporting, no arrests had been made.

Grieving relatives told local media that three men and three women were responsible for the killing.

An image released by officials of four of the suspects names two men as Leobardo and Primitivo and two women as Maria de la Cruz and Nataly.

One relative told local media that the four were jealous after being kicked out of a home so Margarita could move in.

Margarita’s aunt said: “They had problems because of a house that a common relative first left these people in charge of so that they would maintain it, but these people began to rent it and the owner found out and took it away so that Margarita could take care of it.

“That is why they were mad at my niece.”

Margarita had a small grocery store in Cuautla, Morelos state, which was the only source of income for her, her mother, and her three children.

The youngsters have reportedly been left orphaned by her death.

Margarita’s death takes the number of femicide victims in Morelos state this year to 23.

The Instituto de la Mujer (Women’s Institute) in Morelos has condemned the killing and has demanded the immediate arrest of those responsible.
