Authorities say a woman and man are dead after a murder-suicide that spanned from Westchester into the Bronx on Saturday night.

Yorktown police said they received several calls reporting shots fired at Coach-n-Four apartments in Jefferson Valley on Saturday night.

When officers arrived on scene, they said they found a 63-year-old woman, later identified as Geraldine Krecmer, lying on a walkway in front of an apartment with a gunshot wound.

She was pronounced dead at the scene.

"Our officers made the scene safe and located a family member in an upstairs apartment with a small child with her [and] made sure they were safe," said Yorktown Police Chief Robert Noble.

Noble said his officers had to sweep the area because the suspect fled the scene. Landon Veissy said he heard some of the search.

"We were home for the night, with the kids and stuff like that, just in general, we had no plans, but we did hear the choppers overhead," Veissy said.

Police identified the suspect as 51-year-old Salvatore Ciniglio. According to the investigators, he had an estranged domestic relationship with a family member of the victim.

"Ciniglio has a child in common, we believe, with the daughter of the deceased," Noble said.

Noble said information about a vehicle that Ciniglio possibly used was shared with other law enforcement agencies in the area to try and locate him.

Officers from the New York City Police Department were alerted that the vehicle in question entered the Bronx around 10:15 p.m.

NYPD officers located the vehicle a little over an hour and a half later and tried to stop it, but the vehicle fled.

Noble said the NYPD pursued the vehicle and learned that Cignilio was the person who was driving it.

He eventually stopped and shot himself as police approached. He was taken into custody and brought to Jacobi Hospital for treatment, but later died from his injuries.

Yorktown police said they are continuing to investigate the shooting.

Anyone with information is asked to contact them.
