On the evening of January 28, 2018, a first-floor apartment on South 3rd Street in Reading, Pennsylvania, was the scene of a mass shooting. Four young men were shot multiple times; three were pronounced dead at the scene and the fourth died at a hospital. One of those killed was 20-year-old Hispanic male Jarlyn Lantigua-Tejada. The other victims were identified as 20-year-old Joshua Santos, 23-year-old Juan Rodriguez, and 23-year-old Nelson Onofre.

Investigators described the attack as targeted rather than random. The killings were later tied to a violent drug trafficking organization called the Trinidad enterprise, which federal and local authorities said was responsible for multiple violent crimes in the Reading area. In October 2019, a federal indictment named ten members of that organization on charges including murder, kidnapping, drug distribution, and firearms offenses connected to the January 28 slayings.

If anyone knew Jarlyn, his friends, or has information about the events surrounding that night, please share what you know with investigators.
