An investigation into what happened 23 years ago to the baby of Janet Johnson may broaden from cemetery records and hospital documents to actual interviews of employees who were in the delivery room.

"The trail on this is very cold after 23 years," said Murray police detective Alex Huggard.Investigators have given officials at Cottonwood Hospital until July 27 to turn over records associated with the April 20, 1975, stillborn birth of Johnson's fifth child.

The records will include pathology reports on any deceased infants who may have been in the hospital at the same time that Johnson delivered her stillborn baby, Huggard said.

In reviewing records, police are looking at a window of time that includes several days before and after April 20, 1975, the day Johnson delivered the child, he said.

The investigation may also move beyond conversations with hospital administrator Douglas Fonnesbeck, and doctors Jack Batchler and John Harris, all of whom have been subpoenaed, to include anyone who might have been employed at the hospital and may have had contact with Johnson.

"It's a process of elimination," Huggard said. "We take it one step at a time. It's a logical process."

Johnson had the child exhumed last November, sent bones to a laboratory in North Carolina and had DNA testing done on the remains. The lab said the recent tests show the child could not have been hers.

The American Fork mother said she became suspicious of the circumstances surrounding the child's birth after viewing a talk show in which mothers talked about being told their child had died only to find out later the infant had been sold.

Cottonwood Hospital officials have said their records show Johnson did deliver a stillborn baby boy.

Meanwhile, a Bountiful researcher has volunteered to do whatever she can to help Johnson in her quest for information and to examine any documents.

Cathy Millerd said she does adoption searches for people attempting to locate their birth parents, is adept at examining documents and has connection to nationwide adoption specialists.

Police admit the search may, at some point, move to adoption records.
