Authorities called to a Boynton Beach apartment complex early in the morning Monday found a 4-year-old boy wandering around alone.
A Palm Beach County Sheriff's Office report said the boy's mother, Elena Chikaurova, "seemed to think the incident was funny."
Chikaurova and her boyfriend, Pavel Krutakov, were arrested on child neglect charges.
A resident saw the boy and asked where he lived. The boy led the resident to an apartment, but no one appeared to be inside.
As they stood there, a man walked up, grabbed the boy, put him in the apartment and left again.
Chikaurova was passed out inside.
The report said the mother didn't "seem to think it was a big a deal" the boy had wandered outside.
