SONORA, Mex. -- A heavily-armed man was arrested close to the scene of the Mexican massacre in La Mora.
However, Mexican officials are now saying he had nothing to do with the murders.
Mexcian officials say American guns were used to kill those women and children.
In fact, when they arrived at the scene they found 200 shell casings, a scorched car and 2 other bullet ridden vehicles.
Inside those cars were 17 people; 3 mothers and 6 children were killed, 8 others injured.
Now five of the surviving children are being treated at the Banner University Medical Center.
Sustained injuries go from grazes to gunshot wounds to the chest.
Daniel Lebaron tells KGUN9, he cannot even begin to wrap his head around what happened.
“Is this even real. Is this possible. How could somebody murder and burn children...women. Even in the worst wars in history it's almost unheard of. It's devastating,” he added.
He told KGUN9 the massacre was not an accident.
“It was a direct attack. Murder of the worst kind. Beyond description,” said Lebaron.
The murder of the mothers and children is just the latest horror in a region known for cartel violence.
The Lebaron family was traveling in a three car caravan, from their ranch in La Mora to the state of Chihuahua for a wedding. Suddenly, their cars were riddled with gunfire, one erupting in flames.
While several children managed to escape, hiding in bushes for hours, others didn't have the same fate.
“I think tomorrow is going to be a very, very difficult day with funerals and all the kids. It's still a shock,” added Lebaron.
Lebaron’s cousin Rhonita and her four children, including two infants, were among those murdered---Mexican state officials say their blood could be on the hands of a criminal group, possibly a cartel.
Lebaron says he and his family are devastated, but they are hopeful this tragedy brings awareness to organized crime in Mexico and action against it, to bring this violence to an end.
“Hopefully both of our governments finally take this serious and start cooperating on a deeper level to where these kinds of atrocities are stopped,” he told KGUN9.
Now Lebaron says all there is left to do is to stay united, as a family, and continue to speak out against injustice.
