MEXICO CITY — The social media influencer who was shot dead during a livestream on TikTok in the Mexican state of Jalisco appeared to be killed by a hit man and expressed fear before being killed, prosecutors said on Thursday.

The grisly murder of 23-year-old Valeria Márquez on Tuesday shocked the Latin American nation, igniting rumors about the motive behind her killing in a region that’s been eclipsed by cartel violence in recent years. Mexican President Claudia Sheinbaum said her administration is working with local investigators to track down the killer.

Denis Rodríguez, a spokesperson for the Jalisco State Prosecutor’s Office, provided new details on the killing on Thursday, but said prosecutors were still investigating the death of the model and beauty influencer with more than 113,000 followers on the social media app. Rodríguez said that early Tuesday afternoon, hours before the shooting, a masked man posing as a delivery driver arrived at the beauty salon on the outskirts of Guadalajara, accompanied by another man on a motorcycle.
