Crime Stoppers renews $5,000 reward offer in unsolved 2018 West Side shooting death case

Reward offer highlights lingering questions in a 2018 homicide

San Antonio Crime Stoppers is offering a $5,000 cash reward for information that leads to an arrest or felony indictment in the 2018 shooting death of Oscar Alan Thompson II, a case that remains unsolved more than seven years later.

The reward is aimed at generating new tips in a homicide investigators have linked to a late-night shooting on the city’s West Side. Thompson was 25 at the time of the attack.

What investigators have said happened

Police have said Thompson was driving a friend home when an unknown person opened fire on his vehicle at about 2:30 a.m. on Nov. 9, 2018, in the 300 block of Stonegate Drive. Thompson was struck once. Investigators have said he then lost control of the vehicle and crashed into a utility pole.

He was taken to University Hospital, where he later died on Nov. 16, 2018. Authorities have reported no arrests in the case.

How tips can be submitted

Crime Stoppers accepts tips anonymously through multiple channels, including a phone hotline, text messaging and a mobile app. Rewards are typically paid only when information provided leads to an arrest or a qualifying felony action such as an indictment, rather than for tips that do not advance the case to that threshold.

• Phone: 210-224-STOP (7867)
• Text: “Tip 127” followed by the information to 274637
• Mobile: P3 Tips app

Why renewed reward appeals matter in older cases

Public reward offers are commonly used to re-focus attention on older investigations, particularly when initial leads have stalled and investigators are seeking information that may have been withheld due to fear of retaliation, uncertainty about what was seen, or reluctance to get involved. Over time, relationships can change and witnesses may become more willing to share what they know, especially if they believe they can do so without revealing their identity.

In this case, investigators are still seeking information about who fired at Thompson’s vehicle and what motivated the shooting. Even a small detail—such as a description of a vehicle, a person seen in the area, or information about a firearm—can help detectives test or eliminate theories and identify potential suspects.

Investigators have continued to ask anyone with information about the shooting to come forward through anonymous tip channels.

As the case remains open, authorities are encouraging people who may have heard admissions, seen social media posts, or learned details after the fact to submit information that could be corroborated and used to advance the investigation.
