The victims - 37-year-old Troy Shelton and 21-year-old Jackie Pena, both of Newark - were shot in separate incidents on Friday.
No arrests have been made in either case, and authorities were still working Saturday to determine motives for the shootings.
Shelton was shot around 4 p.m. in the area of Grumman and Elizabeth avenues in the city's South Ward and died a short time later, while Pena was shot at a Smith Street residence in the city's West Ward around 10 p.m.
