Family grieved after learning a loved one died in a crash. That’s when they discovered she was “alive and well.”

“During our initial investigation, the NYPD misidentified the victim of a fatal car crash,” police said in a statement obtained by PEOPLE.

A family is still reeling after hearing their loved one died in an accident, only to find out it wasn’t true.

According to WABC-TV, police told Sheila Nagengast that her 44-year-old sister, Denise Owen, died after being struck by a car on Tuesday, October 31, in Staten Island.

“They said, ‘I’m sorry to inform you, but your sister was fatally killed in a car accident,’” added Nagengast, who said her sister was homeless at times and had been diagnosed with schizophrenia.

In a statement obtained by PEOPLE, a spokesperson for the New York Police Department said that “during our initial investigation, the NYPD incorrectly identified the victim of a fatal vehicle collision.”
