According to their classmates, he killed her out of jealousy.
In series of Facebook posts Kal shared before he killed his girlfriend and himself, he described yesterday as his last day as an airman and even wished himself 'RIP'. It is believed that his last post which is '4:36' was the time he killed the young girl.
Most of his Facebook post shows that he may have been obsessed with the girl as he tags her on all his post and has even declared that he could kill for her. Shomzy however stopped tagging him in her Facebook posts since January, 2017 indicating that they may have broken up.
