DENVER -- Psychic Dorothy Allison believed she knew what JonBenet's killer looked like and provided a sketch to the Ramsey family, based on her visions.

The Ramsey family Web site published the sketch, asking the public, "Have you seen this man? This man may have been in the Boulder area in December 1996."

The sketch was also given to Boulder police, who continued to insist that nobody outside the family was likely involved in the crime.

A comparison of the sketch side-by-side with that of a picture of suspect John Karr appears to show remarkable resemblance.

Allison originally came up with the sketch during a 1998 appearance on the nationally syndicated Leeza Gibbons Show. Allison died a year later.

The Ramsey family Web site at www.ramseyfamily.com was used to publish press releases as well as ads and flyers the Ramseys sent out in search for their daughter's killer in the spring and fall of 1997. One of the flyers contained the sketch given by Allison. The Ramsey family let the domain name of the Web site expire in 2004.

Four years before JonBenet's death, Allison assisted El Paso County investigators in the investigation of the slaying of Heather Dawn Church.

''In 30 years, I've never had accurate information from a psychic,'' a veteran law enforcement officer told The Denver Post in 1995. ''But the information by Dorothy Allison was right on the money.''

Robert Browne was later arrested and convicted in the killing of Church. Last month he admitted killing as many as 49 people across the United States.

In another strange twist in the Ramsey case, the man who originally arrested Brown in the Church slaying joined the investigation team looking into the slaying of JonBenet. He said he always believed an intruder was responsible for the crime.
