Mark Hacking told his family something important Saturday — and whatever it is, it apparently makes any further volunteer searches for his missing 27-year-old wife unnecessary.

That news came late Saturday, not from Salt Lake City police but by way of a statement faxed to the Deseret Morning News and other media by Mark and Lori Hackings' families.

"The families understand that Mark Hacking has provided information that makes it unnecessary for individuals or groups to continue the volunteer search," the statement reads. "At this time, the families ask that all efforts from volunteers cease and that anyone with information that they feel might be helpful contact the Salt Lake City Police Department directly."

Salt Lake City police were to meet with family members late Saturday, and the family was expected to share with investigators details of their conversation with Mark Hacking, detective Phil Eslinger said.

"To my knowledge we are going to work through the night with the family to determine what that information is," Eslinger said. "All I know is that it was a legitimate fax from the family. This is not another one of those cruel jokes or rumors."

Police are expected to hold a news conference sometime today.

No further statements are likely from the Hacking or Soares families in the near future. Their statement included a plea that their privacy be respected in what was described in the families' statement as "this difficult time" and indicated they plan to make no further statements about the case.

Contacted at his home Saturday night, attorney D. Gilbert Athay, who has been hired to represent Mark Hacking, said he had no comment.

Lori Hacking disappeared July 19, allegedly while jogging in Memory Grove just before 6 a.m. Volunteers' search efforts in the park and nearby canyons, which over a week drew more than 4,000 people, were unsuccessful.

Police now say they believe Lori, who had just learned she was five-weeks pregnant, was never in the park.

Mark Hacking has been hospitalized since the day after he reported his wife missing. He has also been named a "person of interest" in the case by police but as of Saturday had never officially been called a suspect.

However, investigators took numerous pieces of evidence from the couple's apartment at 127 S. Lincoln St. (945 East), including box springs and computers. Also among the evidence being evaluated by forensic experts is a knife said to have blood and hair samples.
