Where were the parents?
The parents put her to bed and then they went to sleep. Sounds like a reasonable thing to do.
Agree
According to other reports, she was asleep in bed when her parents went to bed around 11:00 pm, and when the father checked on her around 5:00 am she was gone and their door was partly open. Apparently, after her parents went to bed, she was able to open the front door to their apartment and wandered upstairs where someone was having a party. When our oldest daughter was 3, she figured out how to open a deadbolt so I had to change the locks on our house to double cylinder deadbolts (you need a key to unlock the door inside or outside).
Holman Hernandez was at the party and was seen leaving with the girl. The other people at the party assumed that the girl was his until she was reported missing and the police started canvasing the neighborhood.
