A closed hospital floor. A cabinet nobody should be using. A blind count of six.
Sunday night, 12 November 2017. Cascadia Mercy Medical Center sits on First Hill above downtown Seattle. Its eighth-floor north wing closed in August for renovation, and the staff call it the quiet floor. Its automated medication cabinet was never emptied. Maren Ekholm, 44, night charge nurse on 7 West, the unit directly below, has printed three weeks of that cabinet's activity and has an appointment with the pharmacy's diversion specialist on Monday at ten.
At 02:40 she tells a colleague she is going upstairs to count something. At 03:58 a security officer on his round of the closed unit finds her on the floor of the medication alcove, an 18-inch pipe wrench near her feet and the cabinet's screen dark.
The cabinet kept a record of every fingerprint that touched it. A time clock, a staffing schedule, a rapid response team, a pharmacy robot, a truck and a ride-share company kept theirs. Six people had a badge, a reason or a story. Read the records and decide.
Read all 24 documents and name the person who killed Maren Ekholm. One accusation. Right or wrong, the solution file opens and shows every document that convicts. There are no hints and nothing is marked.
