Harrisville, Utah ? A woman jailed in Kansas after allegedly convincing an Indiana couple that she was their missing daughter may have pulled a hoax in Utah, police say.

Authorities in Harrisville say Donna Walker, now jailed in Topeka, Kan., led police on a chase last year after a dispatcher received a cell-phone call from a woman claiming she was going to kill herself and possibly two children with her.

“It was looking pretty desperate,” Police Chief Max Jackson said. “We had everybody looking for this lady and these children.”

Based on the names used in a series of phone calls, Jackson said Walker was behind the hoax.

Police were tipped to Walker’s alleged involvement after authorities in the Pierce County Sheriff’s Office, in Tacoma, Wash., notified Harrisville authorities of the names she uses. Walker is believed to have pulled similar hoaxes in Washington.

During a series of calls last November, a woman, “Debbie Rosenthall,” claiming to be from out of town, was near a Wal-Mart. Police were immediately dispatched to all Wal-Marts in Weber and Box Elder counties.

Shortly after the call, another woman claiming to be the caller’s sister contacted 911 saying she just talked to her sibling, and she intended to kill herself. Police tracked that number to a calling card purchased in Sacramento, Calif. A police sergeant responding to the store called the cell phone and ended up speaking to the woman’s “9-year-old daughter.”

The girl eventually hung up because she wasn’t allowed to talk to strangers on the phone.

“(Walker) already has multiple personalities,” Jackson said. “She can play the little girl’s parts. It just all fits.”

Authorities say Walker, 35, of Topeka, claimed to be Shannon Marie Sherrill, who disappeared 17 years ago while playing hide-and-seek at her home northwest of Indianapolis.
