Surveillance video captured a vehicle consistent with Ryan’s gold Lexus directly in front of the apartment complex where Kamdyn was recovered only minutes before the child was found, FBI agent Samuel Band says in a court compaint filed in Miami federal court Monday.

The complaint accuses Ryan of lying to investigators about his interactions with Cavett on the date of her disappearance.

“The video surveillance did not show Ryan’s car at the pumps where he described it, nor did it show [Cavett] leaving in a dark sedan,” Band says.

Band says Ryan’s phone was examined and showed Google searches on July 26 for “What day does commercial garbage pickup for Hollywood, Florida” and “Does bleach and alcohol make chloroform.”

“According to the National Institute of Health, chloroform is commonly used to incapacitate a victim by rendering them unconscious,” the complaint says.

Ryan calls himself a witch, spiritual adviser, teacher and CEO on his Facebook page.

On Aug. 9, he posted a video stating he was the last person to have seen Cavett but denied being involved in her disappearance.

"Why is it you have a missing woman, and the last person that’s seen her, which is me, who talked to the police, you ain’t heard nothing about me,” Ryan says in the video.

The complaint says in the video Ryan made a statement about covering a window on Cavett’s vehicle with a garbage bag because the window was broken and damaged.

It says surveillance video shows all the truck’s windows intact.
