Costa Rican Police Arrest Four in Killing of Nicaraguan Ex-Military Officer

In Costa Rica, police have arrested four people.

They are suspected of being involved in the killing of Roberto Samcam, a retired military officer from Nicaragua.

Samcam was found dead in his condo.

He was known for speaking out against the Nicaraguan government.

The police have not found the person who planned the killing.

They haven't found any link between the killing and countries other than Costa Rica.

Many Nicaraguans who opposed their government had fled to Costa Rica after protests.

Rights groups say the government used deadly force during these protests, causing many deaths.

Samcam had accused the Nicaraguan military of being involved in the suppression of these protests.
