TAYLORSVILLE — Unified police were searching Tuesday evening for two men they believe are responsible for an "extremely disturbing" attack on a Taylorsville woman.

The 19-year-old woman showed up on the doorstep of her next-door neighbor in extremely critical condition Monday afternoon. Investigators believe Jeffery Hanson, 34, and Eliesa Tupo Olive, 32, tied up the woman for up to several hours and also beat and stabbed her, Salt Lake County Sheriff Jim Winder said.

"There is evidence (the) victim was held against her will," he said.

Hanson lives at the home with the woman at 4428 S. Jared St., but Winder said he's unsure whether the two were romantically involved. Olive is a friend of Hanson's, the sheriff said.

The two men remained at large Tuesday night, and police said they believe they likely are still in Salt Lake County. Investigators want the public's help finding them.

Hanson is described as white, with blond hair and blue eyes, about 5 feet 8 inches tall and weighing roughly 140 pounds. Olive is Polynesian, 5 feet 9 inches tall, has brown eyes and black hair, and weighs about 145 pounds.

Police believe Hanson is driving a red Dodge Durango with a Utah license plate No. E787U.

The two men are being investigated for attempted murder, aggravated kidnapping and aggravated assault, according to Winder. He characterized the alleged attack on the woman as a depraved act.

"I think this is aberrant psychological behavior (that could be) triggered by a number of things," Winder said.

The woman was upgraded to serious condition Monday night and continued to improve Tuesday, police said. She was able to speak with officers about what happened, Winder said.

The sheriff said police are still gathering information about how the woman escaped.

"(We're keeping) the specific chronology of events close to the vest," he said.

Police believe the attack occurred because the men were upset with the victim in a dispute over some property.

Officers stationed themselves outside Hanson's home Monday, preparing for a possible standoff after not getting a response from inside the house. However, they found nobody inside when they entered the home.

Unified police have been called to the home in the past, Winder said.

Hanson was charged in February 2014 with assault and two counts of domestic violence, all class B misdemeanors. Those charges were dismissed six months later. He has no other criminal history in Utah outside of a traffic infractions case in 2004, according to court records.

Olive was charged in November with failure to stop or respond at the command of police and drug distribution with the intent to distribute, both felonies, court records show.

Also in November, in that and two other cases, he was charged with reckless endangerment, theft, interference with an arresting officer, disorderly conduct, two counts of assault, three counts of drug possession and multiple other misdemeanors.

Olive's criminal history also includes a guilty plea to criminal trespass in 2002.

Hanson and Olive are considered armed and dangerous, and should not be approached, according to police. Anyone with who spots them or otherwise has information about their whereabouts is asked to contact Unified police detectives at 385-468-9812.
