Police in Florida are investigating after a 65-year-old woman died from stab wounds she suffered inside a Barnes & Noble bookstore in Palm Beach Gardens. 

The incident involving victim Rita Loncharich happened around 8 p.m. Monday at the Legacy Place shopping center, according to WPTV. 

Witnesses told police that the suspect, 40-year-old Antonio Moore, ran out of the store after stabbing Loncharich, the station reported. Loncharich was found by responding officers inside the Barnes & Noble suffering from a stab wound and later died from her injuries after being taken to a local hospital.

“This investigation is active and ongoing,” the Palm Beach Gardens Police Department said in a statement, according to ABC News. “Investigators are still trying to determine a motive for this attack.”

Jail records from the Palm Beach County Sheriff’s Office show that Moore was booked on a charge of first-degree premeditated murder.

Loncharich’s husband said to CBS12 that his wife called him on her cell phone Monday night to inform him that she had been attacked. 

“We are deeply saddened by the tragic death of a customer following an incident on property,” Legacy Place told WPTV.
