Ferguson, Missouri (CNN) -- As the St. Louis suburb of Ferguson calmed Friday after nights of protests over the fatal shooting of an unarmed black teen, the question remains: Where's the police officer who pulled the trigger? 

Officer Darren Wilson, 28, shot Michael Brown on August 9. The shooting sparked days of violent protests in Ferguson as residents demanded his arrest. 

Separate federal and local investigations are under way, and Wilson -- who has received death threats -- has disappeared from public view.

Here's what is known about his whereabouts. 

Where is he now? 

Few outside Wilson's family and authorities know for sure. 

Wilson owns a house in a modest neighborhood about 20 miles from Ferguson. He bought the house shortly after he was divorced last year, according to the St. Louis Post-Dispatch. 

But several neighbors have told CNN that Wilson left home before his name was released last week. 

What are his neighbors saying about his whereabouts? 

Not much. Most have shunned reporters' requests for interviews, and some put signs in their yards shooing away journalists. 

"We don't know anything ... Pray for Peace," one read, according to the Post-Dispatch. 

"We have 2 children. Do not knock!! No comment," another family wrote. 

Any trails on social media? 

The newspaper reported that Wilson deactivated his social media accounts before his name went public. 

The only social media presence for him now is from supporters, who have set up Facebook pages to support and raise money for him. 
When was that?
