You thought wrong. Read the excerpt!
'The Safe Haven Law in Idaho allows for the surrender of an infant who is unharmed and healthy. Therefore, this was not a legal surrender under state law as it does not meet the criteria for Safe Haven surrender,' a Safe Haven news release reads. Monica Kelsey, the founder of Safe Haven Baby Boxes, said in a social media post at the time: 'We are heartbroken. Anonymity is only allowed when an infant is safely surrendered completely unharmed.'
The perp in this case did NOT leave a baby in the box. The perp left a corpse. You can't expect to leave, e.g., live animals, dead babies, household waste, or anthrax spores in the box and then invoke some "right to anonymity."
