A University of Washington coed is dead and her fellow student boyfriend is being accused of her murder after the pair allegedly took LSD together. The students, Katy Straalsund, 22, and Casey Henderson, 21, bought the drugs on March 20, according to Seattle police. Later that day, neighbors called 911 to report what they thought was a “violent confrontation” coming from Straalsund’s apartment in the University District, reports KOMO News.

When officers entered the home, Henderson was arrested and Straalsund was rushed to Harborview Medical Center. She had no brain activity at that point. The 22-year-old was pronounced dead on March 22, two days after she was attacked.
