HOUSTON, Tx. (CNN) Update: 5/11
Derion Vence, the stepfather who was watching 4-year-old Maleah Davis when she went missing, has been booked into the Harris County jail on suspicion of tampering with evidence, a human corpse, according to the jail website.
Police in Houston have not said whether a body has been found.
Investigators found blood evidence linked to Maleah in his apartment, police said in a news release.
Vence, 26, was arrested Saturday, according to the jail website. A court appearance is scheduled for Monday. Police previously had spelled his first name as "Darion."
Vence has told police that last Saturday he was on the way to the airport to pick up Maleah's mother and had Maleah and his 1-year-old son in his car. On the way, he heard a "popping noise," stopped his vehicle because he thought he had a flat tire and was knocked unconscious by three strangers who pulled up in a blue pickup truck, he told police.
When he woke up a day later, Maleah was gone, he told police.
CNN has reached out to Vence several times this week, but didn't receive a reply. It's unclear if he has a lawyer.
Tampering with a human corpse is a second-degree felony in Texas, which if the defendant is convicted, is punishable by between two and 20 years in prison.
An Amber Alert has been issued for a missing 5-year-old who was reportedly kidnapped by three men in north Houston.
Police said Maleah Davis, her stepfather and his 2-year-old son were reportedly abducted by three Hispanic men Friday night who were driving a blue Chevrolet crew cab pickup.
The stepfather said he was assaulted, and he and his son were dropped off in the Sugar Land area Saturday night around 8 p.m.
The men kept Maleah and drove off.
Maleah is around three feet tall and weighs between 30 and 40 pounds. She was wearing a pink bow in her hair, a light blue zip jacket and gray/white/pink sneakers.
Anyone with information on Maleah Davis' whereabouts is urged to contact Houston police at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
