An offshoot of The Church of Jesus Christ of Latter-day Saints, they are not affiliated with the mainstream church.
Mexican authorities have said the family may have been mistakenly caught in a battle between rival drug gangs, however, others have suggested the family may have been targeted in the merciless attack, CBS News reports.
Loved ones released new video of 8-month-old Brixon who was shot in the chest, and 7-month old baby Faith who was found in her auto seat after her mother, Christina Langford Johnson, was killed has now been reunited with a man identified as her father.

"God will take care of the wicked", Jay Ray, Dawna's father, said in a eulogy.
The driver of the second SUV, Christina Marie Langford Johnson, 31, had leapt out of the vehicle to try to alert the gunman that it was only women and children in the SUVs, but she was shot to death, according to post on Facebook from relative Kendra Lee Miller. "I usually am a very forgiving guy, but this kind of atrocity has no place in a civilised community".
