A 31-year-old man allegedly stabbed a transgender college student more than 40 times in under 10 minutes inside a Seattle student housing complex and left the gruesome scene for her traumatized peers to find.

Christopher Leahy was charged with first-degree murder Thursday for the shocking slaughter of Juniper Blessing, a 19-year-old student at the University of Washington, on Sunday night, KOMO News reported.

The alleged killer turned himself in to Bellevue police Tuesday night following the release of surveillance images on the night of the grisly murder showing his face.

Blessing was found dead Sunday night in the shared laundry room of Nordheim Court Apartments, an off-campus student housing complex close to the UW Seattle campus, according to KOMO.

The King County Medical Examiner determined that the student had been stabbed more than 40 times in her head, neck, shoulders, arms and hands.

Another student was heading into the laundry facility and held the door open for Leahy, who chillingly thanked her as he exited, leaving her to find Blessing’s bloodied body on the laundry room floor. That student called 911 to report the stabbing.

Surveillance footage from cameras inside the off-campus housing complex initially reached investigators with missing chunks after Leahy, who was stalking around the building ahead of the killing, spotted the camera and disconnected its power cord before the stabbing, police said.

However, a Seattle Police digital specialist bypassed the sabotage by extracting the raw data directly from the camera’s SD card.

The recovered timeline showed Blessing and another student using the laundry facility while Leahy repeatedly entered and exited the room.

Once alone, Leahy followed Blessing into the laundry room around 10 p.m., the footage shows.

One minute later, the accused knifeman was captured tampering with the security camera.

He leaves the room for the other student to find Blessing’s body at around 10:10 p.m.

While Senior Deputy Prosecutor Don Raz says that the 40 stab wounds demonstrated an explicit intent to kill, Leahy’s defense attorney Todd Maybrown disputed premeditation and pushed for a second-degree murder charge instead, according to the Seattle Times.

It’s unclear if Blessing was specifically targeted. Other students described Leahy lurking around the off-campus building with at least one female student accusing him of following her.

University of Washington President Robert Jones released a statement Thursday, noting that while the arrest brings a sense of relief to the rattled campus, it cannot lessen the profound shock and grief gripped by the university community.

“I hope the arrest brings some sense of relief to our community,” University of Washington President Robert Jones said in a statement Thursday.

“But this arrest does not lessen the profound shock and grief that the victim’s loved ones and our campus are still experiencing or bring back a beloved, promising and talented member of our university.”

Students set up a memorial for Blessing with flowers and notes.

“It breaks my heart how cruel this world is to some people,” Owen, a second-year student at UW told KOMO.

“This is not a one-off problem. This happens all across our city to all sorts of people, especially towards women, especially towards trans women all the time.”

Sumayya Haly, a second-year student at UW, expressed frustration with the initial delays in releasing surveillance footage.

“I think that like a part of me was a little bit like disappointed at how late the pictures came out, especially with how clear the images were.”

Multiple people, including the suspect’s own brother, identified him to police after the images were released.

Blessing’s family said they were shattered by her murder.

“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 family’s statement obtained by K5 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.”
