A mistaken address that appeared in a 911 computer resulted in a four-minute delay in ambulance service for an elderly Staten Island woman who died before help arrived.
City officials are at a loss to explain the mistake.
The 94-year-old woman’s daughter, Elvira Giuffre, placed a call to 911 shortly after 8 p.m. Thursday after realizing her ailing mother was having difficulty breathing.
She called from a landline — which should have allowed NYPD’s computerized dispatch system to find the home address — and gave her address on Rigimar Court in Staten Island to a dispatcher, NYPD officials said.
The call was transferred to the FDNY as Rigimar Court, the NYPD said. But when FDNY dispatchers pulled the address from their computers, the street came up as Ridge Loop, FDNY officials said.
An FDNY dispatcher asked Giuffre whether Ridge Loop was correct, and she said yes. An ambulance was sent to Ridge Loop first and went to Rigimar Court after the mistake was discovered.
“The operator called me back to say they were at the wrong address, but it wouldn’t have made a difference if they were here,” Giuffre told The Post.
She said her mom “passed very quickly.”
