- Ada County Sheriff's Office
- Bruce Marchant has been formally charged with murder in the death of Sierra/Simon Bush.
Bruce Marchant, 61, was booked Thursday into the Ada County Jail after being extradited from New York. He has been charged with felony counts of first degree murder, first degree kidnapping and rape.
Bush, whose legal name was Sierra but who was called Simon by friends, went missing in late September 2016. The 18-year-old Boise State University student's body was discovered in October south of Idaho City.
A well known figure on the Boise State campus, Bush was a member of numerous student groups and a person of wide-ranging interests and ambitions, from writing fiction to STEM.
"Sierra/Simon was going into aerospace engineering someday; she could do anything," said a friend who spoke at a memorial event at Boise State.
A video arraignment for Marchant is scheduled for Thursday at 1:30 p.m.
