California Woman Accused of Stabbing Two People in Pullman Held on $1 Million Bond

A 29-year-old California woman, identified as Tiffany Dennison, has been arrested and charged with attempted murder and assault for allegedly stabbing two people in a Pullman apartment on Wednesday morning. Dennison is being held on a $1 million bond in the Whitman County Jail.

According to Pullman Police, officers responded to a 911 call from the 1000 block of NE Williams Drive around 8:50 a.m. and found Dennison armed with a large kitchen knife and attacking an adult female inside the apartment. The officers used a taser to subdue Dennison and take her into custody. She appeared to be experiencing a mental health crisis and was calling the male victim the devil during the attack.

The officers also discovered an adult male victim who had been stabbed multiple times while he was sleeping in his bed. He was transported to Pullman Regional Hospital with critical injuries, including a collapsed lung. He is expected to survive. The female victim, who was also stabbed by Dennison as she tried to stop the assault, was treated for her wound at the same hospital.
