Katy Straalsund, a 22-year-old student at the University of Washington, has died from injuries sustained during an alleged attack by her boyfriend, 21-year-old Casey S. Henderson, while the couple was high on LSD.
According to the Tri-City Herald, neighbors overheard a violent confrontation coming from the couple’s Seattle apartment and called the police, who then had to break in and pull Henderson off Straalsund’s nearly lifeless body. The police said Henderson beat and choked Straalsund, and by the time she arrived at the emergency room, she had no brain activity. She succumbed to her injuries on Tuesday afternoon.
According to the police affidavit, Straalsund and Henderson had been dating for approximately six months when they decided to take the psychotropic drug LSD on Saturday afternoon. Via the Tri-City Herald:
They bought the drugs from a person on the street in the University District and walked around the UW campus after taking them, returning to the apartment between 7:30 and 8 p.m. Saturday, Henderson said. He couldn’t account for what happened next.
“He did say that they never slept,” a detective wrote. “He states (that) after a while things ‘started to get weird.’ ”
He became paranoid and imagined his girlfriend was “plotting against him,” the document said. He repeatedly punched and kicked her, using a kick he learned in tae kwon do. He then started strangling her with both hands and remembered yelling, “Do you want to live?”
Several times during the interview, Henderson stated, ‘I thought I killed her,’ a detective wrote.
Henderson is being held on $1 million bail and the police are investigating the case as a homicide.
