A Virginia college student murdered her “best friend” and roommate by stabbing her as many as 40 times with a butcher knife in the off-campus apartment they shared, police said.

Luisa Cutting, 21, from Jeffersonton, Virginia, is charged with second-degree murder for the death of fellow Radford University student Alexa Cannon, formerly of Roanoke, according to a press release from the Radford City Police Department. Cutting was being held in a local jail on no bond. She was scheduled to be arraigned Friday in Radford General District Court.

Police responded to a 911 call around 7:45 Thursday. During the call, a police dispatcher said, she heard someone shouting and referencing a knife, according to a search warrant obtained by the Roanoke Times.

When officials arrived at the off-campus apartment where the women resided, they saw Cutting covered in blood, police said. Cutting put her arms behind her head and said, “Arrest me,” the search warrant said. “I killed her,” Cutting said after police asked her what was going on, according to the warrant.

Cannon was pronounced dead at the scene, the search warrant showed.

Police did not reveal a motive for the killing. Posts on Cannon’s social media pages indicate that the girls had a close relationship.

“I met this girl two years ago online and somehow we ended up living across from each other for a year, this summer she was equivalent to my mom in Cancun. And unimaginably she still puts up with me and now we’re living together next year. Love you more Lu and everyone pray that we don’t kill each other this year,” Cannon said on Instagram in March.

A post on Cannon’s Facebook page from July read: “So incredibly proud of my best friend, Luisa Cutting for becoming Latinos Student Alliance’s President! I know you’re going to be amazing with everything you do! Love you more!!”

“Love you so so much,” Cutting wrote in response to Cannon’s Facebook post.

Cutting is on interim suspension at the university, Caitlyn Scaggs, Radford University’s associate vice president for university relations, told the Roanoke Times in an email.

“This is a tragic moment for our campus community and the Radford family. During this difficult time, we ask that you provide support to your fellow Highlanders,” Radford University president Brian Hemphill said in a statement.

“The days and months to come will also be difficult as we extend our deepest sympathies, as well as our thoughts and prayers, to the family and loved ones of our student,” the statement continued.
