reporter: the calls led nowhere, and jonni felt helpless in oklahoma, so she and her husband packed their bags and drove the four hours down to plano. straight to the parking garage where christina s car had been found. you came straight here. yes. even though this was the one place in dallas where you can pretty much guarantee police had searched pretty thoroughly. yes. but you re searching. you re walking all over the place. yes. as a mom, i just couldn t believe that there s no way that there s no evidence that she didn t come out of this parking garage, that she had to still be here. reporter: jonni didn t find anything but she hoped maybe someone in the neighboring apartments heard or saw something. how many doors you knock on total do you think? oh gosh. 50, 100. reporter: christina s friends were searching the shopping center too.
the plano police department had a disadvantage with the four-day delay start. reporter: zeke fortenberry was a prosecutor in the collin county district attorney s office. plano police department knew that it was four days she d been missing already. and so that kind of raises a red flag that something serious might be going on. there is still no sign of a missing ft. worth woman who vanished from a plano parking garage. reporter: by this time a lot of people in north texas were hearing about christina morris. lorraine caceras covered the story for telemundo dallas. people don t randomly disappear from shopping centers in plano. that just doesn t happen. and the fact that maybe, just maybe this could be a random act. and if it is a random act reporter: then it s really scary. it s very scary. am i the next victim? and the unanswered question, where is she? coming up, questions for the friend who left the party with christina. you don t mind if i look in your car?
