Doesn’t bother Mexican cartel hitmen a bit to shoot a mother next to her 4 day old baby. That and worse happens routinely in Mexico.
They’re back in Mexico, collecting their wages for a job well done.
Mexican cartel would kill the baby too, that's how they roll. The fact that they left the young children alive means it was a professionally group. Kill the adults because they are witnesses leave the kids alive who are too young. I'd bet on a drug dealer rip off gang or a drug partner upset with them.
Were these Ohio folks competing with the Mexican produced grass? That makes a lot of sense then.
Dead families threaten no one
