'Ongoing dispute' led to shooting at Round Rock Juneteenth event, court records say

WILLIAMSON COUNTY, Texas (KXAN) — Court documents detail how investigators are linking a third suspect to a deadly shooting at a Juneteenth celebration in Round Rock.

The shooting, which happened at Old Settlers Park on June 15, resulted in two deaths and 14 injuries, according to the Round Rock Police Department. Police said the victims were innocent bystanders.

Investigators believe the shooting happened as part of an ongoing feud between two "rap groups," documents said.

18-year-old Keshawn Dixon was arrested in Killeen and charged with deadly conduct, a third-degree felony, according to a probable cause affidavit.

Attorney information for Dixon wasn't available Friday. KXAN will reach out to his representative when that information becomes available.

What happened prior to the shooting

Several witnesses told police they saw Dixon in the area of the shooting, wearing a "light grey hoody and a white ski mask," according to the affidavit.

Those witnesses said Dixon was in an "altercation" with another man at the celebration, which stemmed from an ongoing dispute between two groups, court records state.

According to court records, the dispute between Dixon's group and the other man's group stemmed from a member of Dixon's group who was allegedly murdered.

Witnesses told police Dixon "pulled out guns and started shooting" when he and the other man confronted each other, according to the affidavit.

Another witness told police Dixon "fired the switch." In the affidavit, police describe a "switch" as a device that can convert a "semi-automatic pistol into a selective-fire machine pistol capable of fully automatic fire."

The witness told police Dixon "started shooting and lost control of the gun," according to the affidavit.

In the affidavit, the witness said Dixon was allegedly shooting at the man he had a dispute with, who "was in the direction of where the crowd was." Court records state that area is where many of the shooting victims were found.

The investigation

Dixon was previously questioned by law enforcement prior to his arrest, according to the affidavit. While Dixon admitted to being at the Juneteenth celebration, he was "vague as to his whereabouts" during the shooting.

Dixon said he remembered "shots going past his head" when he was in the area of the shooting, court records state. Furthermore, he said he was at the celebration "for only 10 to 12 minutes." He also provided police with his social media account name.

On that account, police saw Dixon and another family member "holding firearms," according to the affidavit.
