Probably determined how the wipe was put down the throat that the 18month old wasn’t capable of doing it. Also says they were left alone for 30 mins not 10, and he took his time calling 911. Not sure how they know that though. Probably a lot of stuff they can’t say until it goes to court. If they could prove he intended to kill the kid he would’ve gotten a more serious charge, so yeah he will probably just end up with some sort of negligence charge causing the child’s death.
