Later when they returned, Tiffany said she didn't know her son's whereabouts. Authorities initially believed he may have hid at her house and conducted a search of the location on Wednesday.

Detectives told ABC13 they uncovered surveillance video from a hotel that shows Tiffany and her boyfriend dropping off Tavores at the hotel.

"She and the boyfriend took him from a location close to the scene to a hotel where he spent the night," Sean Teare, Harris County District Attorney's Office Chief of Vehicular Crimes, said. "She then went to her home and came into contact with sheriff's deputies immediately when she arrived at her house. She initially told them she didn't even know who Mr. Henderson was."

Court documents say that when investigators asked why she lied, Tiffany Henderson said, "because I am a mom."

Prosecutors say Tiffany endangered the public by not sharing her son's whereabouts. Her bond was set at $50,000. She posted bond on Saturday morning.
