Officials didn’t provide details, and the attorney general’s office didn’t respond to a request for comment. The newspaper El Universal cited sources as saying three people were arrested in Bavispe, not far from La Mora.
Mexican authorities have said the LeBarons — an extended family of fundamentalist Mormons with dual U.S.-Mexican citizenship who have lived in northern Mexico for generations — appear to have been caught unawares in a conflict between affiliates of the Sinaloa and Juárez cartels that dominate the rural area. Three mothers and six children were slain in the ambush.
Attorney General William P. Barr is expected to visit Mexico City this week at the invitation of the Mexican government to discuss Trump’s plan.
Julian LeBaron, a family spokesman and longtime anti-violence activist, said the three suspects detained Sunday were low-level “thugs.” He and about 50 other members of his extended family are scheduled to meet with López Obrador on Monday morning.
“We think that’s the reason why they went and picked up these local thugs — so these people can say, ‘Yeah, we did something about this,’ ” he said.
He said the family wasn’t satisfied with the arrests of the triggermen, but wanted the detention of “the people who were responsible for giving the order” to carry out the attack.
The FBI has been assisting Mexico in trying to track down the killers. Last month, Mexican police detained a man believed to have been involved in the attacks, authorities said in the communique Sunday. That arrest wound up providing “critical information and evidence” that authorities pursued.
LeBaron helped lead a march of thousands of critics of López Obrador in Mexico City on Sunday, the first anniversary of the president’s inauguration.
Mexicans were shocked by the attack on the Mormon family, but some have criticized the LeBaron family for calling on Trump to do more to reduce violence in Mexico — including classifying cartels as terrorist groups.
LeBaron acknowledged that many Mexicans worried that such a designation could prompt a U.S. military invasion.
“I don’t think any of us would like to see that,” he said. “But when your sisters and cousins are being murdered, we don’t care where the help comes from.”
