HOUSTON (KIAH) -- Texas Equusearch has been called in to help Houston police with their search for 4-year-old Maleah Davis after the child's stepfather says she was kidnapped by three men after they knocked him unconscious Friday night.
On Monday, volunteers began a thorough search of the area around Greens Road and Highway 59, where her stepfather, Darion Vence, told investigators the kidnapping took place.
We now know that in August 2018, Maleah and her brothers were placed with a relative following physical abuse allegations stemming from a head injury she had.
A judge ordered them to return home in February and called for CPS to check in with the family at least once a month.
The young girl has had several brain surgeries and Sgt. Holbrook with HPD says the latest surgery that happened just a couple of months ago was to help an injury heal. He also said the girl needed a lot of care and had been sick prior to her disappearance.
Vence told investigators he was on his way to IAH airport to pickup the children's mother around 9 p.m. Friday when he heard a popping noise and pulled over to check the tires. Maleah and Vence's toddler son were sitting in the backseat.
The father said a blue 2010 model Chevrolet pickup truck with a crew cab pulled up behind the family on the side of the road.
"[The vehicle] pulls up behind him; two Hispanic males get out— one of them makes a comment, saying Maleah looks very nice, very sweet. The other male hits Darion in the head. Darion loses consciousness," Sgt. Mark Holbrook said.
From there, the father claims he woke up in the back of their truck at some point. 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. His son was still with him, but Maleah was gone.
Vence said he walked along the side of the road and tried to get help, but no one stopped. He ended up at Methodist Hospital in Sugar Land sometime between 10 p.m. and 11 p.m. Saturday. That's when he reported Maleah missing. An Amber Alert was issued Sunday morning.
Investigators said both Vence and his son were treated for their injuries before being released.
The car that Vence was driving, a 2011 silver Nissan Altima with temporary tags, is still missing. The car was was spotted on a traffic camera in Sugar Land around 2:45 p.m. Saturday.
Anyone with information regarding this missing child case should call HPD investigators at 713-308-3600 or Crime Stopper of Houston at 713-222-TIPS (8477).
