Authorities are questioning a group of teens in connection with the murder of a Barnard College student who was stabbed to death during an attempted robbery in an upper Manhattan park, according to a new report.

Police were speaking with the teens following the slaying of freshman Tessa Majors, 18, who was beaten and stabbed at the base of stairs in Morningside Park near West 116th Street and Morningside Drive around 5:30 p.m. Wednesday, ABC 7 reported.

A school security guard called police upon discovering her body, riddled with stab wounds.

Investigators found a trail of blood indicating that Majors had tried to make her way back up the park stairs toward Morningside Drive, police sources said.

Preliminary information suggested that Majors was stabbed several times in the face, neck and under her arm.

She apparently had put up a fight when the thugs tried to rob her, the sources added.

Majors was rushed to Mount Sinai St. Luke’s Hospital, where she died.

Barnard College president Sian Leah Beilock issued a statement about Majors’ death late Wednesday, calling it “tragic news.”

“Dean Grinage and I have spoken to her parents and Tessa’s family is en route to NYC,” the statement said in part. “We are also in close touch with the New York Police Department as they conduct this on-going investigation and seek to identify the assailant in this horrible attack.”

“Tessa was just beginning her journey at Barnard and in life,” Beilock continued. “We mourn this devastating murder of an extraordinary young woman and member of our community. This is an unthinkable tragedy that has shaken us to our core. Please know that we are all grieving together and I am thinking of you as we process this awful news as a community.”
