Rosa Garcia, a 37-year-old Hispanic woman, was fatally shot on March 26, 2017, at the Somerset apartment complex in Fort Worth, Texas. She was shot in the head while attempting to buy a used video game system for her children through the resale site Offer Up; the shooting occurred in front of her husband and 15-year-old son.

Fort Worth Police traced the seller’s Offer Up account to 19-year-old Taejon Horton, who was arrested and found with evidence linking him to other similar crimes. Horton sent a text to his girlfriend the night of the shooting expressing remorse and saying he was leaving the area alone. Authorities say up to three other people may have been involved and continued to seek them.

Family members, including sister Sylvia Garcia, have urged anyone with information to come forward as the investigation continues. If anyone has information about Rosa Garcia’s death or the meeting at the Somerset complex, please share what you know with investigators.
