For families in Mexico searching for missing loved ones, the grim discovery of what is being called an «extermination» site with human remains and ovens, could be their worst fears some true. 

Mexican authorities are now investigating the site in the western state of Jalisco, first found last week by a group of volunteers that was believed, by the volunteers, to have been used by one of the area’s cartels known as the New Generation Jalisco Cartel. 

Inside its iron gates were an increasing number of horrors, including cremation ovens, bone fragments, hundreds of pairs of shoes, clothing and even children’s toys.

«They’d see the shoes and say: ‘those look like the ones my missing relative was wearing when they disappeared,’» Luz Toscano, one of the volunteers, told BBC News. 

The ranch, near the village of Teuchitlán, was raided last September by Mexican authorities who failed to find or reveal the discovery of human remains. 

At the time of the raid, 10 arrests were made, two hostages were released, and a body was found wrapped in plastic. 

After authorities began searching this week, they said they also found almost 100 shell casings.

None of the remains have been identified, and the number is not yet known, but the number of personal items left behind is around 700. 

«The number of the victims that presumably could have been buried there is enormous,» Eduardo Guerrero, a security analyst in Mexico City, told The New York Times. «And it resurfaced the nightmarish reminder that Mexico is plagued with mass graves.»

The discovery, based on an anonymous tip, has dominated the headlines, shocking a country that has become inured by mass graves and promoted citizens to call on authorities to crack down on cartel violence. 

There are 120,000 «forcibly disappeared» people in Mexico. 

Jalisco state Gov. Pablo Lemus told critics in a video message this week that his office is fully cooperating with federal investigators and no one is «washing their hands» of the case, according to BBC News.

The ranch in Teuchitlan, about 37 miles (60 kilometers) west of Guadalajara was allegedly being used as a training base for cartel recruits when National Guard troops found it last September.

Cuba remained largely without power on Saturday morning, after the island nation’s grid collapsed the night before, knocking out electricity for 10 million people and raising fresh questions about the viability of its antiquated generating system.

At sunrise, the island’s grid operator UNE said it was generating only a trickle of electricity – around 225 MW, or less than 10% of total demand, enough to cover some vital services like hospitals, water supply and food production centers.

CUBA WORKING TO REESTABLISH ELECTRICAL SERVICE AFTER SECOND GRID COLLAPSE

Officials said they had begun the process of firing up the country’s decades-old generation plants, but gave no timeline for restoring service.

Cuba´s grid failed Friday evening around 8:15 p.m. (0015 GMT) after an aging component of a transmission line at a substation in Havana shorted, beginning a chain reaction that completely shut down power generation across the island, UNE officials said.

The grid collapse follows a string of nationwide blackouts late last year that plunged Cuba’s frail power generating system into near-total disarray, stressed by fuel shortages, natural disaster and economic crisis.

Most Cubans outside the country’s capital of Havana have already been living for months with rolling blackouts that peaked at 20 hours a day in recent weeks.

Havana was still largely without electricity on Saturday morning. Light traffic navigated intersections with no functioning stoplights and cellular internet was weak or non-existent in some areas.

Abel Bonne chatted with friends on Havana’s Malecon waterfront boulevard early Saturday, taking in the fresh sea breeze after a stuffy night without power.

«Right now, no one knows when the power will come back on,» he said. «This is the first time this had happened this year, but last year it happened three times.»

Severe shortages of food, medicine and water have made life increasingly unbearable for many Cubans, and people have been fleeing the island in recent years in record-breaking numbers.

Cuba blames its economic woes on a Cold War-era U.S. trade embargo, a web of laws and regulations that complicate financial transactions and the acquisition of essentials like fuel and spare parts.

A grid official on Saturday morning said Cuba had been unable to update antiquated transmission and generation components because of the restrictions.

U.S. President Donald Trump recently tightened sanctions on the island’s communist-run government, vowing to restore a «tough» policy toward the long-time U.S. foe.

Havana resident Yunior Reyes, a bike taxi driver, was back on the job Saturday morning despite the blackout, fretting that his food reserves might spoil in the day’s heat.

«We’re all in the same situation,» he said. «It’s a lot of work.»

The government of Greenland called President Donald Trump’s comments about taking control of the country «unacceptable» in a statement Friday.

Officials noted the statement was prompted by Trump’s meeting with the NATO secretary general Thursday, when he reportedly «reiterated his desire for annexation and control of Greenland.»

In response, the leaders of all political parties elected to Inatsisartut, the Parliament of Greenland that includes the Demokraatit, Naleraq, Inuit Ataqatigiit, Siumut and Atassut parties, issued the statement on X.

«We — all the party leaders — cannot accept the repeated statements regarding annexation and control of Greenland,» leaders wrote. «We find this behavior toward friends and allies in a defense alliance unacceptable.»

They added they «must underscore that Greenland will continue serving ITS people through diplomatic relations, in accordance with international law.»

«We all support this wholeheartedly and strongly distance ourselves from attempts to create discord. Greenland belongs to the Greenlandic people, and we (as leaders) stand in unison,» they wrote.

In the country’s recent parliamentary elections, the Demokraatit party defeated Greenlandic Prime Minister Múte Egede’s party, Inuit Ataqatigiit.

Independence from Denmark became a core election issue in Trump’s continued comments about U.S. acquisition of Greenland.

Trump tried in his first term to buy the mineral-rich, key geographical territory in what he called a «large real estate deal.»

TRUMP: US CONSIDERING POSSIBLY BUYING GREENLAND 

Greenland Prime Minister Múte Egede said in January the country was «not for sale and will never be for sale.»

American interest in Greenland dates back to the 1800s. 

In 1867, the State Department looked into purchasing Greenland and Iceland, but after World War II, Denmark rejected a proposed $100 million deal from President Harry Truman.

Acquiring the land would mark the largest expansion of American territory in history, topping the Louisiana Purchase.

The White House did not immediately respond to Fox News Digital’s request for comment.
