According to The Boston Herald, Austin was originally charged with five robberies but a grand jury investigation tacked on four more cases with the aid of additional evidence.

“The Suffolk District Attorney’s office said a GPS monitor Austin was wearing at the time placed him in the area of each of the nine armed robberies when they occurred," WBZ reported. “Austin was wearing the GPS device while free on bail in another case, in which he faced breaking and entering charges.”
