• Analysis: The claim is mostly supported. All sources confirm she was shot during a TikTok livestream at a beauty salon. However, Verification Source #1 and #2 state the city was Zapopan, while the BBC article states Guadalajara. Verification Source #5 states the state was Jalisco, where both cities are located. I will assume the BBC article is slightly inaccurate on the city, but accurate on the state.
