Police find DNA in case of missing Texas woman

ALLEN, Texas - Police searching for a woman missing since August found a "significant amount of DNA" in her former classmate's car, according to CBS DFW.

Christina Morris was last seen on surveillance camera footage at The Shops at Legacy in Plano with her boyfriend Enrique Arochi. On the video, the two people are seen walking into a parking garage.

Arochi was arrested last weekend and charged with aggravated kidnapping. He has maintained his innocence in this case. The whereabouts of Morris are still not known.

CBS DFW reports that according to police records, the DNA came from the blood and saliva of a female and was recovered from the edge of Arochi's car's trunk opening. The police search and arrest warrants suggest that Arochi left the parking garage "with Christina Morris in the trunk" of his car.

The documents state that a phone belonging to Morris was pinging cell towers while she was allegedly locked in the trunk of the car, reports the station. Authorities believe that Arochi even returned to The Shops at Legacy with Morris still inside the trunk.

Arochi was reportedly back at his home in Allen about 40 minutes after the alleged abduction. The warrants also suggest that Arochi had intended to sexually "violate or abuse" Morris, and that he may have become angry when his advances were rejected.

Friends and family members said that they have not lost hope, and still believe that Morris is alive somewhere. They will conduct another search on Saturday.
