A man accused of setting a woman on fire inside a New York City subway train and then watching her die after she was engulfed in flames is awaiting arraignment on Tuesday. Sebastian Zapeta, 33, is facing murder and arson charges in the woman’s death.

New York City police say they have taken into custody a person of interest in the death of a woman who may have fallen asleep on a stationary subway train before being lit on fire by a man she didn’t know.

Prosecutors on Monday charged 33-year-old Sebastian Zapeta-Calil with first- and second-degree murder and first-degree arson in connection with the death of a woman who died after being set on fire in a New York City subway train a day earlier.
