*UPDATE 7/29* Williamson County officials say the parents of the abandoned child has been located. Williamson County Sheriff Robert Chody made the announcement on social media just before 12:30 a.m.
Chody said in a tweet that the mother was not involved in the incident at all and was unaware of what had happened. He says the child's father has also been located and was detained. He says they are investigating and determining the course of action.
The sheriff says that a Twitter follower gave them the lead that led them to the child's parents.
This is an update to a previous story. The original version is as follows:
Williamson County law enforcement officials are working to identify a toddler boy they say was left behind at a splash pad in the Paloma Lake area of Round Rock this afternoon.
Officials say the boy was dropped off by a man in a silver Nissan Altima and when the car drove off it hit a tree and a pole before driving off.
The boy was not in the car during the crash and was not hurt.
Sheriff's deputies say the boy is believed to be about two or three years old and is wearing a white t-shirt and orange shorts. He's not able to communicate who he is to deputies. Sheriff Robert Chody released a photo of the child's face later in the evening on social media.
Officials say the driver of the car is a heavy set Hispanic man about six feet tall and last seen wearing a tan cargo shirt and a striped rainbow collared shirt. He is believed to have been possibly intoxicated.
If you have any information that could help identify the boy or help officials identify the boy's parents you're asked to call 9-1-1 or contact 737-240-0504.
