This is the best summary I could come up with:

Oct 7 (Reuters) - Ecuadorean President Guillermo Lasso announced on Saturday a shake up of the high ranks of the security forces following the killing of seven inmates accused in the murder of presidential candidate Fernando Villavicencio.

Violence, blamed by the government on drug gangs, has sharply increased in Ecuador in recent years and the latest killings seemed to underline rising lawlessness.

Prosecutors said they initiated the investigation because the agency, SNAI, did not carry out a pending order to transfer for security reasons the six inmates killed at the Litoral Penitentiary on Friday.

Lasso was meeting with his security cabinet on Saturday and canceled an upcoming trip to South Korea to "address the crisis in the penitentiary system," according to his official social media account.

Both candidates, business heir Daniel Noboa, who is narrowly leading polls, and leftist Luisa Gonzalez, have demanded the government clarify information about the prison killings.

However, clarity about who is responsible for Villavicencio's murder could, especially if a politician were to be found to be involved, lead to "an ethical and moral shakeup in the country," Espinosa said.
