According to Samantha Koening 's father James Koenig the teen filed a protective order against a man in November but was too scared to follow it through.
"She filed for a restraining order against a person she barely knew and was too afraid to go through with it in court," James Koenig told ABCNews.com last month.
He said he could not elaborate on the situation or the man's identity, but he did not believe that his daughter felt that she was in danger or that someone wanted to hurt her before she disappeared.
When asked if he had any theories about what may have happened to her daughter, he said, "I do, but I cannot divulge."
In November, Samantha Koenig filed the protective order, but she did not show up for a hearing and the order was never issued.
The Anchorage Police Department received criticism for not releasing the surveillance tape, but police spokesman Lt. Dave Parker said they won't do it because, "There's no way this video is going to further the investigation."
Parker said the tape has "evidentiary qualities" that make it valuable to investigators but that it would not be useful to release it because the alleged kidnapper's face is not visible. He said the key to the video for investigators is Koenig's response to the perpetrator.
Samantha Koenig had been working at the Common Grounds Espresso stand for about a month and her father said she was really enjoying it.
"She's a sweetheart. She's got the biggest heart and she has genuine love and care for people. She befriends people so easily," Koenig said through tears. "Everyone that meets her, they call her their best friend. That's just her personality. She's funny and she loves life."
Koenig is the fourth of six children. She has three sisters and two brothers who James Koenig said are working hard to search for Samantha.
Koenig is 5-foot-5 and weighs about 140 pounds. She has brown hair and eyes. Authorities are asking that anyone with information contact the Anchorage Police Department at 907-786-8900.
