Mexico's military says it arrested five men. It ties them to the killing of 10 mine workers. The workers were taken in January in Sinaloa, a state on Mexico's Pacific coast. The ministry says the five men are in a gang. It is a piece of the Sinaloa cartel. But the only charges made public so far are gun charges.

Here is what the military says happened. Four men were arrested on Oct. 16 in El Rosario, Sinaloa. One of the four is from Colombia. A fifth man was arrested the next day in the port city of Mazatlán. The military names him as Jesús Abraham, known as "El Talibán." It says he had weapons and a vehicle when he was arrested.

The ministry links all five men to two cases. One is the kidnapping and killing of 10 workers of the mining company Vizsla Silver on Jan. 23. The company is based in Vancouver, Canada. The other case is a Feb. 3 kidnapping of four tourists in Mazatlán. The tourists were from the State of Mexico.

The 10 workers were Mexican. Armed men took them from the company's camp in Concordia, Sinaloa. Officials say their bodies were later found in hidden graves.

The ministry says the gang is called Los Chapitos. The government says it is run by the sons of the jailed drug boss Joaquín "El Chapo" Guzmán. He is serving a life sentence in the United States. The U.S. calls the Sinaloa cartel a terrorist group.

Now look at the court side. On Oct. 20, federal prosecutors took "El Talibán" to a judge. They charged him with carrying a rifle. They also charged him with having bullets and magazines. Only the military can use all of these. They have not charged him in the miners' case so far. They say they are still looking into it.

His lawyer asked for more time before the judge decides if the gun case moves forward. The judge ordered him held in jail until then. Some headlines said the judge had already ruled. The prosecutors' own statement says the hearing is still going. The other four men are in the hands of federal prosecutors. We do not know what charges they face.

Why did it happen? No one has settled that. In February, Mexico's security chief spoke about four people arrested then. He said they told police the workers were mistaken for a rival gang. The president said that was only what the men in custody said. She said prosecutors are digging deeper.

There were older arrests too. Officials arrested four people in February. In June, they announced the arrest of a man known as "Gabito." They called him a hitman for the same gang.

In April, the company said nine workers were confirmed dead. It said one was still missing. Mexican officials speak of 10 killed. The sources do not explain the difference.

Lawyers for the families asked a federal judge for a hearing. They want the judge to look at what they call failures by prosecutors. The families say they get little news.

Sinaloa is far from the Texas border. Still, U.S. officials say its cartel sends a lot of fentanyl.

Everyone is presumed innocent until proved otherwise.
