BUFFALO, NY (WKBW) -- Neighbors helplessly watched as a 45-year-old female resident of Normal Avenue was stabbed to death by her boyfriend using a samurai sword.
"She was upstairs and she ran downstairs to look for help," said Iris Henriquez.
"A neighbor was opening the door and he was stabbing her," Henriquez said.
Upstairs, the woman's 15-year-old daughter was injured, also stabbed.
The man, who has not been identified by officials, then fled the scene and confronted Buffalo police on nearby Hampshire Street.
"He looked at the cops," said Ray Cruz, who watched the scene unfold from his nearby home. "He charged at the cops. Cops had no choice but to shoot him."
As the suspect held the blood-soaked sword over his head, he was shot at least once when an officer pulled the trigger.
"Officers repeatedly ask him to drop his sword," said Michael DeGeorge, spokesman for the Buffalo Police Department.
"He advances towards the officers and at that point one of the officers discharges his weapon striking him," DeGeorge said.
The department's internal affairs division is investigating, as it does whenever an officer fires a weapon.
The 45-year-old woman was pronounced dead shortly after the incident. Her 15-year-old daughter is hospitalized at Women and Children's Hospital in critical condition.
Police have yet to release their identities.
The suspect is in serious condition at Erie County Medical Center and is expected to make a full recovery.
