Unless Mom works nights, I'm thinking this involved a custody/vistation situation. Otherwise, Mom would have been charged too.
The pothead Dad is identified as HERBERT TUCKER.

Father being charged after toddler found wandering the streets alone overnight
LEXINGTON, Ky (WKYT) - The father of a toddler who was found wandering the streets alone and in his underwear overnight, is in custody.
43-year-old Herbert Tucker was arrested and charged with endangering the welfare of a minor, possession of marijuana and tampering with physical evidence.
Police say someone called them after seeing the child on Duffy Court, off Camelot Drive, early Friday morning.
First responders arrived and covered the three-year-old with blankets to keep him warm.
When police found the toddler’s father at a nearby home, they say he was outside smoking marijuana.
According to a Lexington police lieutenant, the father told officers he was ‘celebrating.’
Firefighters told police on scene that they thought the toddler's core temperature was in a safe area, despite being exposed to the bitter temperatures.
