The case summarized Summary: Teledata expert Terje Lilleåsen has analyzed the mobile data of Tina Jørgensen, who was killed in 2000. Now Aftenbladet reports that, according to Lilleåsen, the mobile phone was most likely destroyed or thrown into the sea by the killer before 02.56 on the night she disappeared. He bases this on the fact that the phone disconnected from the network in an abnormal way, and that it was not switched off, or ran out of power. Lilleåsen cannot be 100 percent sure of the conclusion, but believes this is a qualified guess based on experience from similar cases. Investigation manager in the Rogaland police district, Jan-Olav Våge, believes the new information is interesting for the police. Tina Jørgensen was last seen on Torget in central Stavanger a little more than six hours after she last used her mobile phone. The summary is made by an AI service from OpenAi. The content is quality assured by news’s journalists before publication. This is revealed in a new podcast episode published on Aftenbladet.no, in the series “Death is a man”. In the podcast, Terje Lilleåsen from Telia Norge is interviewed. He has reviewed the activity on Tina Jørgensen’s mobile phone in September 2000. Tina used her mobile phone for the last time at 19.13 on Saturday 23 September 2000, a call that lasted 36 seconds. She was then at a vorspiel near the center of Stavanger. Tina’s mobile phone, almanac and bag were never found. In 2000, the police came out with models that showed what Tina’s missing items looked like. Photo: Alf O. Hansen / Scanpix Tina Jørgensen was last seen on Torget in Stavanger a little more than six hours later, around 01.30. A witness who knew Tina then saw her standing and talking to a man outside Burger King. This man has never reported to the police. This night there was no activity on Tina’s phone until 02.56. Tina’s boyfriend then called her mobile for the first time, but he did not make contact. Her phone was switched off. He then called Tina several times for almost fifteen minutes, with no response. – Not switched off normally According to Terje Lilleåsen, the figures in the overview provide interesting information that has not previously come to light in the nearly 24-year-old murder case. – I can see that the phone went offline and became unavailable, but it was not switched off in the normal way by being turned off or running out of power, says Lilleåsen in the podcast. One of the reasons why Terje Lilleåsen can say this is an analysis of the numerical data in the table below: Tina Jørgensen last used the phone at 19.13. On the night of the murder, her boyfriend tried to call her from 2.56am. Photo: The police To the right of the date column are the times when Tina was tried to be called. The numbers on the far right in the yellow field show the column for the length of the calls. Lilleåsen manages to get interesting information based on the time it took before the call was forwarded to voicemail. From the table we see that this took four seconds the first time the boyfriend tried to call Tina at 02.56.21. The next few times it also took three or four seconds. Only active data in 2000 If the phone had been registered online, i.e. switched on, it would have taken around 20 seconds before the call was forwarded to voicemail, according to Lilleåsen. And if the mobile phone had been switched off, or run out of power, it would have been immediately diverted, according to Lilleåsen. In other words. If everything were normal, the numbers in this column should be either 0 or approximately 20. – What does this mean? – Based on the mobile data, it appears that Tina’s mobile phone has either been smashed or thrown into the water, says Lilleåsen, according to the podcast. Tina Jørgensen, on the left, was only 20 years old when she was killed by an unknown perpetrator. Here she is with her friend Katrine Sønneland. Photo: Private Terje Lilleåsen elaborates on this to news. He says that when the numbers show three or four seconds, this means that the mobile phone has gone off the network in an abnormal way. The phone does not have time to notify the mobile network that it “disappears”, i.e. ends up in water, or is destroyed in other ways. The mobile network tries twice to connect the phone without success, and each of these attempts takes a couple of seconds. – Another indication that Tina’s mobile phone was not switched off normally, or ran out of power, is that the phone carried the location of the last base station with it for more than a day, says Lilleåsen to news. He goes on to say that at the time, more than 20 years ago, mobile phones could only be tracked on active data. Today, passive data will also be recorded, movements without the phone being in use, which gives the police a much better hand. The police: – Interesting information Lilleåsen says that he cannot be 100 per cent sure of the conclusion, but that this is a qualified guess based on experience from similar cases. Most likely it is Tina’s killer who has destroyed or removed the phone in this way, and it must therefore have happened in a time span of around one and a half hours before 02.56. According to Jan-Olav Våge, head of investigations in the Rogaland police district, the new information is interesting for the police. – New theories about timing are always important to us, and this will be taken into account further in the work, says Våge to news. For the record: It was not Tina who called from her mobile phone at night, even though it says “Exit” on the calls. These were calls from others that went to her voicemail.
