Bone-chilling new security footage has captured a 31-year-old man stalking a transgender University of Washington student inside an off-campus laundry room — just minutes before he allegedly stabbed the victim 40 times.

The disturbing video shows Christopher Leahy repeatedly entering and exiting the laundry room at the Nordheim Court student housing complex in Seattle on May 10. He eventually remained alone with 19-year-old Juniper Blessing, a student from New Jersey. According to authorities, Leahy then unplugged the security camera before allegedly stabbing the victim to death.

The King County Prosecuting Attorney’s Office also released additional surveillance videos showing Leahy attempting to open doors at several homes in the neighborhood in the days leading up to the incident.

“Police indicate that there were attempts by the defendant to try to enter private homes in Ravenna in the days before the homicide,” said Casey McNerthney, a spokesperson for the prosecutors’ office.

“There was at least one other campus building that police say he attempted to get into before the death of Juniper on the 10th,” McNerthney added.

Leahy, who is not enrolled at the university, turned himself in to police on May 12 after authorities released security camera images of him at the scene. He has been charged with first-degree murder.

The newly released footage shows Leahy entering the laundry room behind another student at approximately 9:45 p.m. He soon left, only to return around 10 p.m. At that time, Blessing was sitting on the floor in front of a dryer, with a male student standing nearby.

Leahy looked directly at the camera upon entering, then quickly exited again, followed by the male student, leaving Blessing alone in the room. Prosecutors say Leahy returned once more and deliberately unplugged the security camera.

According to court documents, Leahy “appears to follow the path of the power cord with his eyes and head from the camera around the wall above the doorway.”

Minutes later, another student entered the laundry room and found Blessing bleeding on the floor. The student immediately called 911.

Leahy was scheduled to appear in court on Thursday, but the hearing was postponed after his attorney requested additional time for mental health evaluations.

The victim’s family released a statement describing Juniper Blessing, who was born Michael Carneiro da Cunha Blessing in Princeton, New Jersey. The family said she moved to Santa Fe, New Mexico in 2018 and attended the New Mexico School of Arts until 2024.

“Our family has been shattered by the loss of our child, Juniper Blessing, to an act of unspeakable violence near the University of Washington campus in Seattle,” the statement read.

“Juniper was simply the most amazing human being we have ever known – highly intelligent, extremely talented, and deeply sensitive to the needs of others. Juniper’s loss not only devastates us but diminishes the world.”
