A former lead detective in the JonBenet Ramsey murder case says he believes the murdered girl's mother wrote the ransom note that was in the family home the day her body was found.
In an interview airing Monday on ABC-TV's "Good Morning America," Steve Thomas, who resigned in protest of what he called the lack of aggressive prosecution of the case, said Patsy Ramsey wrote the note.
Of 73 suspects whose writing samples were analyzed by experts, only Patsy Ramsey could not be excluded as the note's author, ABC quotes Thomas as saying. ABC released part of the interview Saturday.
Six-year-old JonBenet was beaten and strangled. Her body was found in the basement of the Ramsey home in Boulder, Colo., on Dec. 26, 1996, about seven hours after the rambling three-page note was found.
Thomas interrogated the Ramseys four months after the slaying and was a lead detective until he resigned in August 1998, saying Boulder County Dist. Atty. Alex Hunter sacrificed procedure for politics.
Thomas has written a book, "JonBenet: Inside the Ramsey Murder Investigation." He is scheduled to appear on ABC programs this week to promote it.
He said Patsy Ramsey changed her handwriting after the slaying.
