A NEW York man charged with killing a woman by tossing a Molotov cocktail on her in an elevator has told police he was angry because she owed him $US2000 ($A2,009).
Jerome Isaac was arrested on murder and arson charges in the death of 73-year-old Deloris Gillespie.
The 47-year-old Isaac reeked of petrol 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, Mr Browne said.
The suspect had been waiting for her when the elevator doors opened to the fifth floor of her building, police said.
