Casper Police are keeping open minds about the possibilities with the disappearance of Kristi Richardson, Capt. Steve Freel said Friday.

“We are looking at this from both sides,” Freel said at a press conference.

We're looking at this as an investigation that could potentially turn into a criminal investigation," he said.

We are looking at it from the potential of a person that walked away from a house and has yet to be found because maybe they they don’t want to be found.

“But the flip side of it is that we’re looking at this as an investigation that could potentially turn into a criminal investigation,” Freel said. “We would hate to think that it would end up in a bad manner but it could up in where the end of this we have a body.”

Richardson, 61, is 5-feet, 4-inches tall and weighs less than 100 pounds.

Her last known contact was 7:45 p.m. Monday with a member of her company, according to a search warrant affidavit filed with Natrona County Circuit Court on Thursday.

The search warrant was executed to determine if there may be "evidence which may show or tend to show the crime of murder or abduction and the cause and manner of injury" and if there is any "evidence which may also show or tend to show motive for the crime of murder," according to the affidavit.

Tuesday, police searched her house and found a cell phone in her bed, her purse with a large amount of cash, and identification on the kitchen counter, according to the affidavit. "There was no immediately identified evidence of foul play."

However, the affidavit states officers were told a garage door opener usually kept in her purse was missing, and they observed stains on the sheets that could possibly be blood or urine.

The affidavit did not state whether any vehicle belonging to Richardson was missing.

Police spoke with friends family and neighbors, but they didn’t have any idea of the her whereabouts. Volunteers have conducted searches in the area around Richardson's house on East 24th Street.

Police also searched Richardson's office at Richardson Trucking at 6850 W. Yellowstone Highway, and recovered a computer and files from the office, according to the receipt of the search warrant.

Freel cautioned not to read too much into the evidence that has been found.

Investigators have been sifting through an overwhelming number of leads, and detectives will be working on the case throughout the weekend, he said.

The family is distraught and wants help, he said.

“Their focus is to get her home,” Freel said.

Anyone with any information about the case is urged to call the police department at 235-8278.
