Late Friday they arrested a woman in connection to her fall.

Sienna Edwards died Thursday after falling 14 stories from the balcony of an apartment on East 179th in the Tremont section.

Police now believe that the 20-year-old fell while trying to escape a group of women who were threatening to kill her, after apparently mistaking her for someone else.

Edwards' boyfriend told reporters she had gone to the home as a favor for her boyfriend, who needed help delivering birthday presents to his 3-year-old daughter. The boyfriend is not allowed in the apartment because the mother of his daughter has an order of protection against him, sources said.

Late Friday, police arrested the little girl's mother, Kenya Edmonds, on murder and manslaughter charges.
