UPDATE SEPT. 26: Shaquilla Stafford has been identified as the suspect in Monday's crash. Among the charges include battery with a deadly weapon and possession of a gun with altered serial number.
Stafford has been released on $18,000 bail. Officials say she's related to Asa Brown, the man standing trial in the September 2016 shooting death of 47-year-old Jessie Bush.
The injured woman is identified as Bush's sister. Police say she received a leg injury in the lunchtime crash.
The incident is also raising concerns about security.
Although the Regional Justice Center is Clark County building, the sidewalk in front of it belongs to the city of Las Vegas. The city told 13 Action News us they're planning on installing bollards in front of the sidewalk on 3rd Street that would block cars from jumping the curb and preventing a similar incident from happening.
The Associated Press contributed to this report.
