Scott Spencer says the 2-year-old boy's mother had asked a friend to drop off the child with the boy's father in Spring because the mother was in the hospital.
Police say the boy's father, who identified the boy as 2-year-old Royal Simmons, said that the friend dropped his son off at a neighbor's home instead of his house. When the child did not show up, the father assumed the plans had changed so he left his home for the evening.
The sheriff's office posted an update Thursday morning saying that the boy's father has been located.
She also left two bags she was carrying on the woman's doorstep before she drove off in a white vehicle, officials said.
In the 23-second-long clip, a smiling woman could be seen leaving the child and knocking several times.
"When Deputies arrived they viewed video surveillance and observed a black female arrive at the residence in a white passenger auto".
Reporters who were in the neighborhood Thursday spoke to a man who identified himself as the boy's father after recognizing his child from the doorbell video. Spencer, who is a father, said the video was disturbing to watch. Authorities say it will be up to CPS on if the child will be returned to his parents.
In August, the same sheriff's department issued an appeal after another chilling video showed a semi-clothed woman wearing wrist-ties rushing up to a doorbell in the middle of the night.
This all happened at 8:20 p.m. Wednesday, October 17.
According to the sheriff's office, authorities received a 911 call from someone who said she went to answer a knock at her door and found a child standing there alone.
She now faces a charge of child abandonment, a felony, CBS Dallas-Fort Worth reports. At this point the identity of the suspect and the child are unknown. The child is now in the care of Child Protective Services as authorities try to find his family.
Spencer said the boy was in good spirits and was placed in the custody of Child Protective Services.
The boy remains in the custody of the state as the investigation continues.
