A violent attack on a South Third Street row house in Reading, Pennsylvania, took four lives on the night of January 28, 2018. Twenty-three-year-old Juan Rodriguez was among four young men found shot inside the residence; the others were Jarlyn Lantigua-Tejada, 20, Nelson Onofre, 23, and Joshua Santos, 20. Three died at the scene and one later at a hospital.

Investigators concluded the killings were not random. Authorities tied the quadruple homicide to a violent drug trafficking organization and reported the motive as part of a turf dispute within the local drug trade. The apartment was described as the scene of a targeted, coordinated shooting.

What additional information about these victims or this neighborhood could help piece together why this location became a locus for such deadly violence?
