Anyone tried pinging his cell phone? Find my phone app?
Carrier might be able to tell you his last location.
Good luck!
His phone goes straight to voicemail. I'm assuming it's turned off. When you call it, the voice mail of my brother gives another number and he says his phone is broken. I called the other number and it goes to his work supervisor. I talked to him and he said he hasn't seen my brother in weeks and is worried about him as well.
