A woman stabbed two of her children to death, wounded a third and then tried to kill herself at her house in the Mexican Gulf coast state of Veracruz, EFE reported on Tuesday.
The 35-year-old woman was despondent over her financial and personal situation, the state Attorney General's Office said on Monday.
The incident occurred on Sunday in Tres Valles, where Ofelia Parra Romero put her children in bed and slashed their throats, then tried to cut her own throat.
The woman's husband, Alvaro Aburto Cruz, arrived a few minutes later and tried to save the four, but he was only able to save the couple's two-year-old daughter, Naciel, and his wife.
Naomi and Bruno, ages 5 and 4 respectively, died, an official said.
Parra Romero, who is in stable condition, was conscious and gave a detailed statement to the authorities.
The woman said she was not sorry about the crime and wished she had been able to finish things off.
Parra Romero said her husband drank, beat her frequently and did not give her money to care for the children, prompting her to end her family's suffering.
