Sabrina Cammock's autopsy was conducted Sunday, but the results were awaiting further studies, medical examiners' spokeswoman Julie Bolcer said.
Police say there were no signs of criminality when Cammock was found at around 9:20 a.m. Saturday at the Hotel Edison. The hotel declined to comment on the death, first reported Saturday by the Daily News.
Specializing in sprinting, Cammock competed as recently as the previous weekend, when she was on the women's 4x400 relay team at the 2015 ACC Indoor Championships at Virginia Tech, according to Syracuse's sports website.
"Sabrina was a wonderful and remarkable person and student-athlete," Syracuse track and field coach Chris Fox said in a statement Saturday. "Our team and coaching staff are devastated by her loss."
Cammock, a senior, was studying public health at Syracuse's David B. Falk College of Sport and Human Dynamics, Dean of Student Affairs Rebecca Reed Kantrowitz said in a statement. The university is on spring break.
Cammock had recently done an internship involving medical quality assurance in an oncology unit, giving a presentation about the subject as part of an internship symposium at her school in December.
A member of a school record-setting 4x100-meter relay team, Cammock won a Syracuse scholar-athlete of the week award last April. She also was named to the 2012-13 Big East conference All-Academic Team.
As a high-school student, Cammock ran for The Mary Louis Academy, a Catholic girls' school near her home in the Jamaica Estates section of Queens.
"She's better than anybody you know," her cousin Kemal Brown told the Daily News. "She's a baby, and she's gone."
