Thursday’s Östgöta Correspondent reported that a woman has said she saw a suspicious man hanging around the scene of the murders several times in the days leading up to them.
“It is unfortunately the case that some people are reluctant to contact the police,” said detective Nils Ahlberg.
“They are afraid of being drawn into the murder investigation. But for us it is of enoprmous importance that anybody who could have made the slightest observation gets in touch.”
According to the Östgöta Correspondent, the woman saw a man in his late twenties and wearing a beige jacket and a blue or black hat. The description is similar – but not identical – to other witness reports from the time, as well as from an anonymous letter which police received soon after the attacks.
“The witness has explained that the man would stand in the same place for a couple of hours without doing anything,” said Nils Ahlberg.
“The observations were made between 8 and 10 in the mornings.”
The murders on 19th October 2005 stunned the town of Linköping. The assailant stabbed 8 year old Mohammad Ammouri, who was on his way to school, and 56 year old Anna-Lena Svenson, who was only 25 metres from her apartment block and on her way to her job in central Linköping. The boy died at the scene and Mrs Svenson died from her wounds in hospital some hours later.
The murderer escaped but police found his blood-stained clothes hidden near the scene of the murder and concluded that the killer had seriously injured his own right hand in the attacks. DNA samples were taken from the clothes as well as from the so-called butterfly knife which was found shortly after the murders.
Police have reissued their appeal for information and Thursday’s Expressen reported that they are currently focusing on four “high interest” individuals.
