Police obtained Monday a picture of missing University graduate student Cayle Bywater, taken the day of her disappearance.

The photo of Bywater, 29, was taken by an undisclosed person in Memorial Park, where she was last seen Dec. 29, according to a news release issued by the Athens-Clarke County Police Department.

The picture was released the same day the family held a news conference at the Athens-Clarke police station. Bywater’s sister Tiffiny Cohen, mother Valery Bywate and sister Kristen Bywater asked for the public’s help.

Cohen told the Athens Banner-Herald Tuesday she fears her sister may have been abducted.

“It’s not in her nature to wander or not know where she was,” Chohen told the newspaper. “She’s never done this before. She’s never had bouts where she disappeared before. I fear someone got her. Someone could have her alive somewhere. … Something’s happened where she’s not in control.”

Police have not uncovered any signs of foul play thus far in the investigation.

The picture, taken at roughly 4 p.m., shows Bywater standing in the background near a swing set with her dog, Oliver.

Bywater is 5-feet-3-inches, has red curly hair and weighs about 115 pounds. She was last seen wearing glasses and a blue sweatshirt or jacket with a red stripe across the sleeves and chest, blue jeans and slip-on Van brand shoes, according to the photo.

“If we get additional information, we will expand our search, but at this time, we don’t have any specific information on other possible search areas,” said ACC Det. Dustin Smith, lead investigator on the case.

Police have searched the wooded areas and lake of Memorial Park, the release said. They also have searched the trails of the University’s intramural fields.

Smith asks anyone who visited Memorial Park Dec. 29 or 30 to contact him at 706-613-3888, ext. 795.
