President Barack Obama called for an “open and transparent” probe into the shooting of unarmed black teenager Mike Brown, but investigators have often been anything but transparent. Over the past several days, local law enforcement has withheld certain details about the case or offered accounts of what’s happening on the ground that differ from what witnesses describe.  

The public, state officials and the family of 18-year-old Mike Brown all want answers as to what exactly occurred between Brown and a Ferguson police officer on Saturday that led to the teen being shot multiple times. Here’s what information law enforcement has failed to offer about the case.  

The results of Brown’s autopsy. St. Louis County police revealed Tuesday that the autopsy confirmed Brown died of gunshot wounds, but they would not say how many times the 18-year-old was shot. Police offered no other details from the autopsy report.

How many protesters have been injured. “Nobody got hurt” during confrontations between police officers and protesters, Ferguson Police Chief Tom Jackson told reporters in Ferguson on Thursday. However, pictures making their rounds on social media show otherwise. Protesters display bruises and injuries from rubber bullets, wooden bullets and bean bag rounds. At least 10 people, including three officers, have been injured in the aftermath of Saturday’s shooting, KMOV reported.  

Why two reporters were arrested. Several reporters have been arrested during the protests, but law enforcement has offered little reason why. “We asked to speak to a commanding officer,” Washington Post reporter Wesley Lowery wrote of being arrested in a McDonalds in Ferguson on Wednesday. “We asked to see an arrest report. No report, the officer told us, and no, they wouldn’t provide any names.”

The officer’s name. Police have refused to release the name of the officer who shot Brown, citing fear for the officer’s safety. Law enforcement said the officer involved had been placed on administrative leave.
