Man killed by police after stabbing woman, police dog

From the Associated Press:

SAN DIEGO -- San Diego police shot and killed a knife-wielding man on Friday after he
fatally stabbed a woman believed to be his wife and wounded a police dog.
Police went to the home in the Paradise Hills neighborhood after a woman called to report a man threatening to kill himself and brandishing a knife, said police Lt. Terry McManus.
A man came to the front door and threatened to kill police. He also made statements that led
officers to believe he had slain his wife inside, McManus said.
Officers entered the house led by a police dog. The man stabbed the dog before two officers shot him, McManus said.
Police then searched the house and found the woman had been stabbed to death.
The victims were not immediately identified.
The police dog, a German shepherd named Earp, was taken to a veterinary hospital and was expected to recover.
