Sienna Edwards may have been pushed to her death from high-rise

                 Sienna Edwards plunged to her death - possibly while running for her life.   

A 20-year-old woman may have been pushed to her death from an upper balcony at a Bronx hi-rise Thursday night, police said.

The woman, Sienna Edwards appears to have been involved in a confrontation with three other women — including her boyfriend’s ex-girlfriend.

Edwards had gone to the 14th floor apartment on E. 179th St. as a favor to her boyfriend.

Under terms of an order of protection, he cannot go near his ex-girlfriend, police said.

But he wanted his current girlfriend to drop off birthday gifts for his three-year-old daughter.

The child was inside the apartment, as was her mom — the ex-girlfriend — plus the ex’s sister and a friend when Edwards arrived at about 9:30 p.m.

After a short time, Edwards called 911 “looking for help,” Police Commissioner Ray Kelly said Friday.

“In the background there are voices that say ‘You’re not going to leave here alive, you’re not going to leave here alive,’’ Kelly said.

The dispatcher, hearing that message up to six times, but not hearing anything from the caller, notified police.

Officers were sent to find the apartment but were unable to trace the cell phone call any closer than a block away from where Edwards died.

About about 10 p.m., the ex-girlfriend called 911 and reported that Edwards had committed suicide by jumping over a five-foot high balcony.

Detectives are skeptical.

“The investigative premise is she may have been pushed from that balcony or fell trying to escape individuals who were trying to kill her,’’ the source said.

It does not appear the child witnessed the incident.
