“All we look for is something that doesn’t fit in,” says Jack Boggess with Texas EquuSearch. “We look for clothing, shoes, whatever. Just something that doesn’t fit in, and that’s what we key on.”

Friends and family of missing 4-year-old Maleah Davis are focusing their search on Sugar Land today in the area surrounding Vence’s workplace.

Vence, the ex-fiance of Maleah's mother, is charged with tampering with evidence, specifically a human corpse.

Vence was due to appear in court yesterday, but the hearing was rescheduled. Yesterday, a judge also lowered Vence's bond from nearly $1 million to $45,000.

Anyone with information that might help solve the case of Maleah’s disappearance is asked to call Crime Stoppers at 713-222-TIPS. You can leave an anonymous tip.
