The shattered family of a suspected ISIS supporter killed by police say dashcam footage proves he didn't deserve to die. Raghe Abdi, 22, was shot dead by police when he allegedly lunged at them armed with a knife on Brisbane's Logan Motorway early on Thursday morning. Abdi, who had allegedly been influenced by Somali extremist group al-Shabab, was on bail and had previously been arrested by counterterrorism officers. Police say Abdi is directly linked to the deaths of a 87-year-old man and an 86-year-old woman, whose bodies were found with significant injuries in a home at Parkinson on Thursday afternoon. Muslim community leader Ali Kadri revealed freshly obtained dashcam footage from the motorway showed Abdi with his hands in his pockets - just moments before he was killed.
