Salvador murder suspects killed
Four policemen killed in Guatemala jail

Four Guatemalan policemen arrested in connection with the murders of three politicians from El Salvador have been killed in jail, police say.

They were shot dead inside the maximum security Boqueron prison, east of Guatemala City.

A riot is reported at the jail, with several officers taken hostage.

The bodies of the three Salvadorean lawmakers and their driver were found in their burnt and bullet-ridden car near Guatemala City last Monday.

The four high-ranking policemen had been held in Boqueron prison since their arrest on Thursday.

"It is confirmed that the four bodies are them," police spokeswoman Maria Jose Fernandez said.

Photographs of their bullet-ridden bodies were distributed outside the jail.

3 politicians of the ruling Party liquidated by police officers one of which was head of an anti-organized crime squad.

The alleged killers arrested 3 day later, then killed by armed gun men while in maximum security prison.

Not much to go on; no indication if either was involved in US funded subversion or in resisting that subversion.

I'd think that one was on one side, and the other on the other side - yet it seems as though both sides used equally deplorable methods. I think that's peculiar.

As far as i know the current Guatemalan govt is 'US friendly', but no doubt there are some good guys there to.

Could be a setup: the politicians were being inconvenient, liquidated, the killing blamed on law enforcement officers who were also being inconvenient, who are then also liquidated.
