Round Rock Police Chief Allen Banks announced June 20 that Ricky Thompson III, 17, was arrested as one of the participants in the Juneteenth mass shooting that killed two people and wounded an additional 14.

Police are also searching for additional suspects from the incident, which occurred at the Old Settlers Park in Round Rock.

What happened?

Thompson, from Manor, was found in Pflugerville and taken into custody by the Lone Star Fugitive Task Force.

He’s been charged with aggravated assault with a deadly weapon, a second-degree felony. However, Banks said more charges are likely to be brought against Thompson.

What else?

Banks said the investigation is still ongoing and asks that anyone with any information about the shooting or potential suspects contact the Round Rock Police Department.

“We have a lot of work to do,” Banks said. “We know Ricky Thompson was not the only shooter at this event. We are still looking for other suspects. We are still continuing to gather all evidence, continue to talk to witnesses and we’ll continue to do everything that we can to bring everybody involved to justice."

Anyone with information about the incident is asked to contact Detective Maio at 512-341-3135, or email [email protected]. The department has also requested the public to upload any photos or video evidence by visiting this website.

Gov. Greg Abbott announced June 18 the Office of the Governor’s Public Safety Office is offering a reward of up to $10,000 for information leading to the identification or arrest of anyone involved in the shooting. The Williamson County Crime Stoppers and Bureau of Alcohol, Tobacco, Firearms and Explosives have also each offered $5,000.

Tipsters with any information can call the Texas Crime Stoppers hotline at 1-800-252-8477 or submit a tip online through the Texas Department of Public Safety. All tips are anonymous, regardless of how they are submitted. Officials also urge citizens to not attempt to apprehend a potential fugitive.

The conditions

This was the 16th year the city of Round Rock has hosted the Juneteenth celebration, structured as an open park setup with a stage.

According to a city representative, there were “numerous security measures” in place, including over 22 law enforcement personnel assigned to the event and a centralized on-site command center.

“Officers and volunteers were spread throughout the park with specific monitoring duties, and two Skywatch Towers were in place with personnel monitoring the event from a higher vantage point,” said Sara Bustilloz, city of Round Rock communications and marketing director, in a statement to Community Impact. “The Round Rock Fire Department was also present with personnel and equipment to provide on-site medical response if needed. The agencies at city events regularly engage in training to respond to a variety of incidents, including shootings. In preliminary discussions following the event, it is clear that these measures enabled a swift and comprehensive response by first responders that saved lives of innocent bystanders.”

What residents should know

The city of Round Rock will host a Fourth of July parade along Mays Street in two weeks, with plans to host several other outdoor events throughout the year. According to Bustilloz, these events are expected to remain open and free to the community.

“Additional safety measures have been incorporated into these events throughout the years, and we will continue to evaluate these measures as we have for all events in the past,” she said. “Although the city cannot eliminate all possible risk, staff takes the safety of our community seriously and are deeply saddened that the suspects involved felt the need to endanger innocent bystanders with their senseless actions.”
