Records show 18-year-old Patrick Scott has been charged with unlawful carrying of a weapon as a result of Wednesday's incident in the 10800 block of Richmond Avenue.
The Houston Police Department says Scott and fellow suspect Brayden Smith were arguing when the shooting broke out.
According to HPD, Smith fired the shots that killed 25-year-old Caitlin Stup and injured a teenager.

According to court records, new details have emerged that the principal of Elsik High School informed an Alief ISD gang resource officer that she had recognized Scott in a media release as one of her students who attended Elsik High School.
Smith was also scheduled to appear in front of a judge on Friday morning, but failed to do so because he was "being uncooperative," according to court officials.
Meanwhile, it was revealed in Scott's court appearance that he was already out on bond for an unrelated aggravated robbery case.
Prosecutors say Scott wasn't allowed to carry a weapon as one of the conditions of that bond.
In a statement to Eyewitness News on Friday, METRO said it was working with law enforcement to investigate what happened and to increase visibility and patrols in the area where the shooting occurred:
"First and foremost, our hearts are with the victim's family and everyone affected by this tragic incident.
METRO understands that events like this are frightening, and we want riders to know that their safety is our top priority. We are working closely with law enforcement to investigate what happened and to increase visibility and patrols in the affected area.
We encourage riders to report anything suspicious to the bus operator, METRO Police, or through METRO's customer service channels. If something does not feel right, we want to know about it so we can respond.
While no transit system can prevent every act of violence, METRO has measures in place to support rapid response and investigations. Surveillance footage from the bus was successfully downloaded and reviewed by law enforcement, which will be hugely beneficial to the apprehension of the suspects.
Key safety measures include:
- Expanded patrols by the METRO Police Department across buses, trains, platforms, and transit centers.
- New satellite police substations at key locations to improve visibility and shorten response times.
- METRO's Safety Partnership, which places METRO Police alongside HPD, the Harris County Sheriff's Office, constables, and other agencies to provide coordinated coverage.
- Use of onboard cameras, platform cameras, and real-time monitoring to support investigations and rapid response.
- Continued investment in lighting, station design, and shelter improvements to increase visibility and comfort for riders."
