The parents of two young children, Perez and Arzuaga were gunned down Saturday night amid Puerto Rican Day festivities in Humboldt Park. Arzuaga, 24, died that night and Perez, 25, Tuesday morning. Shortly after learning of her death, the couple’s friend Jae Pacheco reflected on their love story. “I thought it was so cute,” Pacheco told the Sun-Times. “They first met each other at a party, and it was over with from there. They fell in love with each other, and they spent years together. They made a family together.” “It was love at first sight,” she added.
