Jerome Isaac, of Brooklyn, was arrested Sunday on murder and arson charges in the death of 73-year-old Deloris Gillespie. The 47-year-old Isaac reeked of gasoline when he entered a police station overnight and implicated himself in Gillespie's death, New York Police Department spokesman Paul Browne said.
Gillespie was ambushed in the elevator of her Brooklyn apartment building on Saturday afternoon, Browne said. The suspect had been waiting for her when the elevator doors opened to the fifth floor of her building in Prospect Heights, police said.
"It was apparent he knew she was on the elevator," Browne said.
After setting Gillespie ablaze, Isaac went to his apartment building just blocks away and set a fire there, Browne said. He then hid on a roof before turning himself in to police, Browne said.
