Collins Jumaisi Khalusha (an confirmed ISG member) is a Kenyan suspected serial killer, who escaped police custody in August 2024. He was arrested after 10 bodies were discovered in Nairobi. He allegedly confessed to the murder of 42 women, including his wife, Imelda Judith Khalenya. He escaped police custody along with twelve undocumented Eritrean migrants, after being allegedly assisted by insiders. Eight officers, who were on duty at the time have since been suspended. Kalusha pleaded not-guilty to manslaughter, with his lawyer claiming he was tortured to falsely confess. Khalusha allegedly murdered 42 women, ranging in age between 18 and 30, over a two-year period, with the first being his wife by dismembering and mutilating.
