Relatives of those sufferers told NBC News that a motorcade comprising many families was assaulted Monday, together with three automobiles getting shot and yet another group on fire.
The families' account of the attacks and subsequent efforts to recover the surviving children include reports of shooting from the hillsides that continued well after dusk.
When they found her, the "first thing she told us is, we have to go back for the others", said Lenzo Widmar, a cousin of Rhonita Miller's who helped with the rescue. She turned to Facebook to share the vicious episode.
"All of a sudden, bullets just rained from above, from on top of a hill, down on top of them", Langford said.
"My dad, Andre and couple of uncles and relatives went to check up on the vehicle".
"There were remains inside and outside of the vehicle". Her mum, 29-year-old Christina Langford Johnson was murdered in the attack.
She had been shot to death but her seven-month-old daughter, Faith Marie Johnson, was discovered uninjured in her vehicle seat. At some point, the vehicle caught fire and exploded.
Christina Langford Johnson was found a few metres from her van after trying to leave her driver's seat and wave her arms to show she wasn't a threat.
Before she had gotten out of the vehicle, she seemingly placed her young 7-month-old daughter's carseat hastily on the floor, saving the infant's life. "And so away she went", Langford said. She was gunned down.
The survivors, according to LeBaron's posts, are Kylie Langford, 14, who was shot in the foot, Devin Langford, who was not injured, McKenzie Langford, 9, who was grazed by a bullet in her arm, Cody Langford, 8, who was shot in the face and the leg and is now hospitalized, Jake Langford, 6, who was not injured, Xander Langford, who was shot in the back and Brixon Langford, 8 months old, who was shot in the chest.
All of the dead and wounded had dual USA and Mexican citizenship, family members said.
Bullet-riddled vehicles that members of the extended LeBaron family were traveling in sit parked on a dirt road near Bavispe.
In 2009, Benjamin LeBaron, an anti-crime activist who was related to those killed in Monday's attack, was murdered in 2009 in neighboring Chihuahua state.
Miller said the family was told that if the bullet had gone a quarter of an inch deeper into Brixon's chest, he would have been killed.
The oldest Langford sibling, 14-year-old Kylie Evelyn Langford, was shot in the foot and stayed with the younger siblings.
"His jaw is broken".
A third SUV - about 10 miles behind the other two - had been headed to an airport in Arizona, Miller said. "He is actually in a more serious condition than they thought". Under the circumstances, I think they are being champs."A 7-month-old girl, Faith Johnson, was also among the survivors.Her mother, 29-year-old Christina Langford Johnson was killed in the attack.Miller said the baby was found in her auto seat, uninjured.She is now back in La Mora with her grandmother".
"[They] are pretty calm", Miller said. "Last night, Devin was in shock, a little bit confused and just exhausted after a terrible, long day. Under the circumstances, I think they are being champs".
