2 Canadian tourists fatally stabbed in Atlantic City

Two Canadian women visiting Atlantic City were stabbed to death Monday morning in an apparent robbery attempt in the heart of the gambling resort city's tourism district, according to reports.

The victims, whose names have not been released, were described by the Philadelphia ABC News affiliate WPVI as being 80 years old and 47 years old.

There were no details about where they were from in Canada, nor were there details about how the victims may have been related.

The Associated Press reported that the tourists were fatally stabbed during a botched street robbery in broad daylight. According to an NBC-affiliated news crew in Philadelphia, the crime scene was in an area near the Bally's Atlantic City hotel and just steps away from the AtlantiCare hospital.

A female suspect remained in custody early Monday night.

Tried to snatch purse

Antoinette Pelzer, 44, was arrested around 10 a.m. ET after a police officer witnessed the altercation.

Witnesses said the suspect tried to steal one of the victims' purses and that the attack was unprovoked.

An officer happened to come upon the violent scene and drew his gun, ordering the suspect to drop the knife, which she did. He then arrested her.

Pelzer was initally charged with two counts of aggravated assault and weapons offences, but Atlantic County prosecutor Ted Housel said it's likely her charges will be upgraded after the two women died from their injuries shortly after the incident.

Both women were stabbed multiple times in the upper body, police said.

Investigators were working Monday night to determine how long the victims had been in the New Jersey gambling and leisure resort and where they had been staying.
