NEW YORK -- A 28-year-old man has been arrested for killing his mother with a bomb he mailed to her in a hollowed-out cookbook, authorities said today.
Craig Kipp was arrested Sunday at his Brooklyn home by police and U.S. Postal inspectors after a three-month investigation, a police spokesman said.
Police said Kipp was initially charged with a federal postal violation for mailing the deadly letterbomb, a Sears cookbook which had been rigged to explode when his mother opened it.
Police said Kipp was in the custody of federal authorities and would be arraigned later today.
Joan Kipp, 54, died May 7, a few hours after the bomb exploded as she was opening the package addressed to her and postmarked from Staten Island.
The bomb was accompanied by a scribbled note that threatened that Mrs. Kipp's husband and two children would be next. The note read, 'Howard, Craig and Doreen will be next.' Howard is Mrs. Kipp's husband, and Doreen is her daughter.
The device contained a six-volt battery, wiring, explosive powder and three .22 caliber bullets. When Mrs. Kipp opened the book, two of the bullets stuck her in the left side of the chest, fatally wounding her.
Mrs. Kipp worked for the City Board of Education for 15 years and was supervisor of guidance of School District 20 in Brooklyn. She was also treasurer of the Bay Ridge Community Council, an umbrella organization representing 96 neighborhood and religious groups.
Authorities gave no motive for the slaying.
