SAPD identifies murder suspect in June 2025 downtown shooting that killed Allan Roquemore, 32
Suspect named months after deadly confrontation near North Alamo Street
San Antonio police are seeking 25-year-old Walter Whiten in connection with a fatal shooting that occurred downtown in June 2025, an investigation that now includes allegations of both murder and aggravated assault.
The shooting occurred in the 700 block of North Alamo Street, a corridor near nightlife venues and heavy pedestrian traffic. Investigators said a confrontation preceded the gunfire: Whiten and 32-year-old Allan Roquemore were seen talking and arguing shortly before shots were fired.
Police said Roquemore was shot multiple times and pronounced dead at the scene. Investigators allege Whiten pulled a handgun during the encounter, fired at Roquemore, and fled before officers arrived or could make an arrest.
What charges mean at this stage
The case is being pursued under two separate felony counts: murder and aggravated assault. The murder allegation reflects the death of Roquemore. The aggravated assault allegation indicates investigators believe at least one additional person was threatened or harmed during the same episode, or that the circumstances of the shooting met the legal threshold for an assault charge involving a deadly weapon.
Police have not publicly detailed the role of any other victims, witnesses, or participants, and have not released additional information about a possible motive beyond describing the argument observed before the shooting.
How investigators are asking the public to help
Authorities are requesting information on Whiten’s whereabouts and are directing tips to the San Antonio Police Department’s Homicide Unit. Detectives are also taking information directly through an assigned investigator.

- Detective Goodwin: 210-207-7674
Context: why identifying a suspect later can happen
In homicide cases, investigators may identify and name a suspect weeks or months after an incident as witness accounts are collected, surveillance footage is reviewed, and forensic evidence is processed. Naming a suspect also typically indicates investigators believe they have developed probable cause sufficient to support an arrest on specific charges.
Police are asking anyone who knows the suspect’s location to contact investigators directly.
As of Wednesday, Jan. 28, 2026, police had not announced an arrest in the case.
