The 16-year-old Connecticut student from Jonathan Law High School who allegedly was stabbed to death by a classmate after she rejected his prom invitation has been identified as honor student Maren Sanchez.

Maren was stabbed to death at the high school in Milford around 7 a.m. Friday.

“We are obviously devastated by the loss of one of our students,” Elisabeth Feser, Milford superintendent of schools, told CBS New York. Feser told the Hartford Courant that Maren was popular among her classmates at Jonathan Law.

"She was an athlete, she was in the National Honor Society. She helped out with other athletic teams. She was very well respected and liked," Feser said.

Maren was involved with an argument with the suspect, who reportedly stabbed her because she declined to go to the junior prom with him Friday night. While police wouldn’t publicly identify the suspect because he’s a minor, the New York Daily News identified him as 16-year-old Chris Plaskon. The paper said Maren was his ex-girlfriend.

Police wouldn’t confirm those reports, however.

“Our investigators are conducting a large number of interviews and looking at other measures as well to determine not just why this happened, but how it happened,” Milford Police Chief Keith Mello told CBS New York.

Chris used a kitchen knife to fatally stab Maren in the neck, witnesses and police told the Daily News.

"She was screaming," a friend of Maren’s who witnessed the crime told the paper. “There were students in the hallway when it happened. The kids who saw it are all a wreck.”

Maren was taking to a hospital, where she was pronounced dead.

The suspect is in custody, the Hartford Courant reported. He was first detained by school staff and the school resource officer.

Maren posted a picture of herself in her prom dress March 2 to the JLHS Prom Dresses 2014 Facebook page. “Yay so excited!!” she wrote in the post.

Jonathan Law students were dismissed from school Friday so police could investigate the scene.

Student Sean Chester told the Courant that Maren was also her class president and a member of the Key Club.

"Everything you're doing right in high school she was doing," he said.

The girl’s death caused “Maren” to trend Friday on Twitter. Many users of the social media site expressed outrage and condolences about the stabbing. Jonathan Law students urged their classmates to wear purple to school Monday as a tribute to Maren.
