Vence and Davis were riding in a auto with Maleah's 2-year-old brother.
He then made the report that his daughter Maleah was missing, but now isn't being viewed as a suspect, the investigator said. He reportedly told police he was in and out of consciousness until he came to around 6 p.m. Saturday near Highway 6 in Sugar Land. He heard a popping noise like a flat tire, and stopped.
Holbrook asked that anyone who might have seen Vence, the Nissan Altima or the three men in the pickup truck contact authorities.
The girl's mother called another family member to meet her at the airport when Vence failed to show up, and then alerted police Saturday morning after not hearing from him, reports Houston TV station KTRK. That's when he reported Maleah missing.
The auto Vence was driving - a silver Nissan Altima belonging to Maleah's mother - is also missing, police said.
Houston Police say Maleah Davis, 5, disappeared May 4.
Police said they were able to look at the license plate of the vehicle (pictured) that Vence was driving.
The stepfather, identified as Darion Vence, said he was knocked out, and went in and out of consciousness.

Guardiola will be hoping the Belgian is fit for their final encounter which could possibly decide the Premier League title. Fernandinho is also a significant doubt for City and could be replaced by Ilkay Gundogan in the holding midfield position.
"She's needed a lot of care", the police sergeant said.
A blue pickup then pulled up behind them, Vence told authorities, and two men got out of the truck.
"He begins walking around", Holbrook said.
Authorities also do not know the license plate of the kidnapping auto. "If you have her, just please drop her off somewhere safe".
Traffic cameras captured a photo of the Nissan driving through an intersection Saturday afternoon. "I would love to know more about that".
"We're hoping the public can give us any information about anybody who has seen Darion during that period of time because he doesn't really know where he was or what's going on there", Holbrook said. I'd love to know where this vehicle is because somebody drove it. "And I don't want to speculate". They handed out at least 100 missing person flyers throughout the Sugar Land area in Houston, Sunday. The group of five women, friends of Maleah's mother, resumed their efforts Monday and were joined by Texas EquuSearch.
"She's a spunky little thing, you know, and she's handsome".
Maleah, who stands 3 feet tall and weighs 30 to 40 pounds with brown eyes, was last seen wearing a pink bow in her black hair, a light blue zip-up jacket, blue jeans and gray, white and pink sneakers, say police.
