AUSTIN, Texas - UPDATE: The charges against the 15-year-old and 17-year-old have since been dropped by the Travis County District Attorney's Office. Authorities say they are looking for a new suspect in connection to the deadly 6th Street shooting that happened on June 12.
Court documents obtained by FOX 7 Austin Wednesday indicate the Sixth Street mass shooting may have started as a dispute between rival groups of teenagers.
The teens had a violent history with each other, according to Austin Police.
Police say a teenage boy who suspected another 17-year-old he knew from middle school went out on Sixth Street with a group of friends and family Friday evening. The 17-year-old is suspected of shooting the boy in the leg in Killeen a few days prior.
The group posted about the outing on social media. Shortly after, police say the 17-year-old posted that he was also going to Austin.

"There was just pure chaos out there. A crowded street, several individuals armed with firearms." said attorney and former Travis County Judge Charlie Baird.
13 people were injured in the shooting. Police say most were innocent bystanders. Doug Kantor, 25, of Michigan was killed.
"This was two rival members of groups that were having a problem with each other and decided that they were gonna have a stand-off in the middle of a street… my brother was caught in the crossfire," said Doug Kantor’s brother, Nick Kantor.
