The man accused of burning to death a 73-year-old Brooklyn woman has pleaded not guilty.

Prosecutors say Jerome Isaac sprayed Deloris Gillespie with gasoline and lit her on fire inside the elevator of her Prospect Heights building. Gillespie's family says they believe the motive was a dispute over money.

Isaac's next court date is scheduled for April.
