 That's right. They have not identified a motive yet. They also haven't identified an ideology connected to Crooks. There's a lot of that really right now. The FBI says it hasn't found any social media posts or writings that contain violent or threatening language. There's no indication that Crooks had mental health issues, no criminal record. It appears that he acted alone. The FBI says that it has interviewed nearly 100 people so far in this investigation. It's finished searching Crooks' home and vehicle. It now has access to his phone.
