FAIRBANKS, Alaska — A Fairbanks woman suspected in the stabbing death of the father of her children was arrested after stabbing a woman and stealing her pickup, police said.

Lindsey Preshaw is charged with attempted murder, felony assault and vehicle theft in the stabbing Wednesday of a 66-year-old Ester woman, the Fairbanks Daily News-Miner reported.

She’s also the primary suspect in the stabbing death Tuesday of her stepbrother, John Preshaw III, the father of her children, police said.

Police found John Preshaw dead inside a south Fairbanks home and identified Lindsey Preshaw as a potential witness in the case.

Lyndsey Preshaw in 2013 was charged with stabbing John Preshaw in the leg with a butcher knife and sentenced to 20 months in prison.

Early Wednesday night, according to investigators, Lindsey Preshaw attacked a woman in Ester, stole her pickup and fled south.

The woman told Alaska State Troopers she arrived at her Parks Highway home and saw a woman walking down the exterior stairs of her home. She told the woman to leave.

The homeowner parked, walked toward her house and again saw the woman, later identified as Preshaw. As the woman turned, Preshaw stabbed her in the back, neck and face, causing suffered life-threatening injuries, according to troopers.

Preshaw climbed into woman’s truck and insisted the wounded woman accompany her as she drove south on the Parks Highway. About three miles down the road, the woman persuaded Preshaw to let her out. A man found the injured woman and called emergency responders.

Troopers found the truck crashed in a ditch about 10 miles (16 kilometers) south of Ester. Just after 9 p.m., a man reported a woman acting strangely along the highway about 5 miles (8 kilometers) north of Nenana. Troopers contacted Preshaw. Her clothes were stained with blood and seized as evidence.

Preshaw is represented by the Alaska Public Defenders office, which did not respond Friday to an email request for comment and routinely does not comment on open cases.
