Authorities are not investigating the family? How does this child wander out of a house? Don’t the doors have locks?
Could be a million things. The usual crappy mom but even other factors. Kids sleepwalking for instance, have know kids to do this right out the front door even in dead of winter.
It happens. I was on a run one day when I saw a neighbor 3 year old alone in the street. I asked him where he lived and he ran home. Then I saw a dog and figured that it was part of the same adventure. When I took the dog home Mom was horrified to find out the kid had gotten out too. They put slide locks 5 feet up to stop the little runner and he figured out how to defeat those too.
Have you ever been a parent?
Kids can figure out door locks and medicine bottle lids in s heartbeat.
Both of our boys walked out of the locked house when they were little ones. Honest to goodness, this happens.
A 5 y.o. can open a door. But what compels a 5 y.o. to leave the house at that time is the real questionr.
