Where is Typhenie Johnson? The Fort Worth woman had a good job, close family ties, and a bright future when she disappeared in October 2016 while meeting her former boyfriend, Chris Revill.

Revill was later convicted of her aggravated kidnapping, but Johnson's whereabouts remain unknown.

The CBS News Texas I-Team spent months piecing together the mystery, from the minutes leading up to her disappearance to the years of searching that followed.

The case comes down to a 90-minute window: that's how long Revill was gone immediately following Johnson's disappearance. Where did he go? Why were her clothes found strewn around his backyard? Why was he sweating when he returned to the scene? And what about the other missing woman tied to Revill?

This documentary, which is expected to debut on the CBS News Texas streaming channel next month, includes audio interviews from the early hours of the investigation, along with interviews with Fort Worth detectives, Tarrant County prosecutors, family members and others who are committed to finding Johnson.
