Salt Lake City police released pictures of airport surveillance cameras on Tuesday, saying they are the last known images of a student who disappeared more than a week ago.
"We have no evidence that could indicate a bad game, but it's all about the lack of that character," Deputy Police Chief Tim Doubt said.
Mackenzie Lueck, 23, a native of El Segundo, California, and a senior at the University of Utah. landed at Salt Lake City International Airport on June 17 and then drove Lyft to a park where she was presumably hit by someone in a car.
"We see no indication that she has left the net before," Zweifel said. After talking with Lück's family and friends, the police have stated "that this kind of behavior is atypical for them".
The police are also unsure if they are in danger. "I would like to say again: Mackenzie, if you just want to be left alone, please let us know that you are safe," Zweifel said.
Lueck attended a funeral in California before traveling to Salt Lake City. Doubt has said. She missed a midterm check and was in for a scheduled flight back to Los Angeles on Sunday, police said, "Doubt said. He said that the video does not show how she talks to anyone. You can see her walking from the jetway and stopping to pick up luggage.
The police claimed that the Lyft driver and the carpool had been cooperative, and the driver said when Lueck was dropped she did not appear to be in any emergency.
But Zweifel said that the description of the person she should have met is vague, and the police do not know if it was a man or a woman and can not confirm the make and model of the other vehicle.
The police, according to Doubt, had three interactions with Lueck: a move in 201
"Our detectives continue to work around the clock in this case, noting that Mackenzie remains a very important player for us," he said.
Zweifel said police are searching social media or other digital accounts that she may have. The police said she had received about 125 tips over a telephone line, and Doubt called on anyone who had information or had contact with them to contact the police.
Officials also want to hear from anyone who knows who met them at Hatch Park.
Lueck is a part-time enrolled at the university and studies kinesiology, pre-and underage health care. The university said it cooperates fully with the search.
"The University of Utah is deeply concerned about the well-being of Mackenzie & Kenzie & Lueck and our thoughts are with their family," the university said in a statement on Monday.
