On the night of May 3, 2014, 50-year-old Jeronimo Lopez of Guatemalan origin was shot in the abdomen during an armed robbery at his Walker Street apartment in Fairview, New Jersey. The gathering at his home was a clandestine card game he reportedly hosted to save money for a return trip to his native country. Lopez was taken to Hackensack University Medical Center and died during surgery from his injuries.

Police say a group of armed men stormed the apartment, forced about a dozen people to the floor and robbed them of cash and jewelry. Investigators later arrested four suspects: Evens Dumas, 20; Blonson Florestal, 19; Keshawn Malone, 21; and Jose Rivas, 25. Authorities identified Dumas as the triggerman, Rivas as the person who allegedly provided information about the card game, and described Malone, Dumas, and Florestal as members of the Sex Money Murder sect of the Bloods, while Rivas was described as an alleged MS-13 member. The four faced charges including murder, armed robbery and weapons offenses.

What additional information about the night or the people present might help explain how the robbery escalated to lethal violence?
