Police gunfire struck bikers involved in last May’s Waco shootout that left nine people dead, according to evidence that will be presented to a grand jury.

However, it remains unclear whether any of the officers’ shots caused any of the deaths, reports the Associated Press, which reviewed over 8,800 pages of evidence. In June, Waco Police Chief Brent Stroman said three officers fired 12 shots on the scene.

The shootout involved two rival motorcycle gangs, and began over an altercation involving one person rolling over another’s foot with a bike. In addition to the nine deaths, 18 people were injured and 177 arrests were made.

According to the AP, the evidence report includes previously undisclosed information about the shootings, such as testimony from witnesses, audio of interactions with police and videos taken of people fleeing the violence.
