In the meantime, an autopsy is still pending to get the family's cause of death.

Now, loved ones say their main focus is to get the family back home.
"They're still in Mexico and they're going to be performing an autopsy and definitely getting to the root of what caused their deaths," Jacobo told KBAK. "So we're not sure about any specifics at this time."
A GoFundMe has been set up to help raise funds to bring them home.
The couple also leaves behind three other children.
