Casey Cooke, University Of Oklahoma Student, Found Dead On Campus (VIDEO)

A senior at the University of Oklahoma was found dead on the Norman campus after allegedly falling from a fire escape, according to her family.

Casey Cooke, 22, was found unresponsive east of Evans Hall, the central administrative building on campus, shortly before 3 a.m. on Sunday morning by university staff that patrol the area, reports KFOR.

OU spokeswoman Catherine Bishop says emergency crews responded and administered CPR, but were unable to resuscitate Cooke.

Authorities do not believe Cooke’s death was a suicide, and her body has been sent to the crime lab to determine the cause of death.

Cooke’s family told KFOR that she was climbing a fire escape to get to the roof when she slipped and fell to the ground. Her uncle said it is still unclear why she was climbing the fire escape alongside Evans Hall.

Cooke was a pre-med zoology major pursuing a second bachelor's degree in Spanish. Richard Cooke, her father, said she was applying to do volunteer work at free medical clinics in preparation for medical school, and had planned on earning her degree at the OU Health Sciences Center in Oklahoma City. She was also a member of the Pi Beta Phi sorority,

"She shined bright and was always beaming from ear to ear," Cooke’s sorority sisters wrote in an email. "She was there for anyone in an instant and always had the nicest and most positive things to say about people.”

A funeral service has been scheduled for June 7 at Chapel Hill United Methodist Church in Oklahoma City. Cooke’s parents are asking that people make donations to the church in lieu of flowers.
