TIFFANY GILLESPIE'S boyfriend wasn't happy that she was pregnant with his baby, so early yesterday he shot the 24-year-old mother of two in the head, leaving her dead in the basement of her South Philadelphia home, police said.
Gillespie's mother found her at 2:40 a.m. with a single gunshot wound and called police to the house, on Mildred Street near Ritner. Gillespie's two young children and other family members were in the house at the time of the slaying, police said.
