NEW YORK -- A Brooklyn school supervisor was fatally injured Friday by the explosion of a bomb in a hollowed-out cookbook delivered to her home, police said.
The victim, Joan Kipp, 54, died at Lutheran Hospital about two hours after she opened a package containing the cookbook that had been delivered to her home in the Bay Ridge section, police said.
They said she had sustained hand and chest wounds.
Police were uncertain of a motive in the attack.
'We're investigating every possible angle,' Capt. Jack Clark said. 'We are not ruling out anything.'
Authorities said Mrs. Kipp was running for vice-president of the Bay Ridge Community Council. She was the treasurer of the council.
Mrs. Kipp had been employed by the city's Board of Education for 15 years.
Police said the explosive device consisted of a 6-volt battery, wiring and explosive powder.
Clark said the package was delivered about noon by the U.S. Postal Service.
'She was not home at the time it was delivered. She was at work,' Clark said. He said Mrs. Kipp was alone when the explosion occurred. Her husband, Howard, was not home.
