Enrique Gutierrez Arochi was charged Monday with the second-degree felony. His bond has been set at $100,000.
According to court documents, the case involves one of Arochi's former co-workers who claims she had a sexual relationship with him when she was 16 and he was 22.
It lasted about six months and during that time she occasionally slept over at his parent's home in Allen.
Arochi told his parents she was 17. They even gave her a birthday cake with 18 candles on it for birthday, the document states.
The case will go before a grand jury on Thursday.
Arochi was arrested and charged with aggravated kidnapping in December 2014 in connection to the disappearance of 23-year-old Christina Morris.
Morris was last seen Aug. 30, 2014, and Arochi was seen on surveillance video walking with her into a parking garage at the Shops of Legacy in Plano.
Arochi's December arrest came after police said DNA samples collected earlier in the investigation from his car were a match to Morris' DNA.
Prior to his December arrest, Arochi told FOX 4 in an interview that he was not involved in Morris' disappearance.
