son, and that he hadn't been a violent person. However, his girlfriend and his sister did tell investigators they both had noticed Abdus-Salaam displaying paranoid behavior recently, both independently claiming they had spoken to him and urged him to seek help for his mental health. Despite this, there was no record that he ever was diagnosed with, or sought any treatment for, any mental condition. For a short time, it was suspected Abdus-Salaam may have been connected with an earlier (and still unresolved) knife attack on a nurse in Millington, Tennessee, in October 2019. He was later confirmed to have been uninvolved, being far away from the town at that time.
