Sparks detectives say they are reviewing several hours of surveillance video from seeking clues into the disappearance of 64-year-old Judy Calder.
Calder is an associate professor in the department of Human Development and Family studies.
She and her husband live in Incline Village, but Calder was staying at John Ascuaga's Nugget in Sparks the weekend she disappeared.
Family members also say she requires medication for diabetes and high blood pressure.
Investigators say her brown 2000 Lexus was found near the university August 19th, and that a person described as a dark-skinned male may have been seen driving it earlier that day.
