"Any attempt to identify these victims puts them at risk," Investigator Trevor Materasso with the Westminster Police Department said in a statement Friday.
Investigators are looking for a possible connection between abduction of the jogger at Ketner Lake Open Space on May 28 and a similar incident in July 2012.
"Due to the ongoing investigation and consideration there is an unidentified predator on the loose, it is a top priority for the police department to protect the identity of the females in both of those incidents," Materasso said.
The suspect in the Memorial Day case is described as follows:
- Light skinned male
-18 to 30's (or someone who may look that age)
-5 feet 6 inches to 5 feet 8 inches (Height can vary above or below these approximations)
In the attempted abduction case, the woman reported that a man grabbed her from behind and placed a rag over her mouth that had a chemical smell.
The FBI and the Behavioral Analysis Unit are asking the public to contact authorities if anyone around them changed their behavior, acted unusual, failed to show up for a family activity or other change that was unusual on Oct. 5 and days after Jessica's disappearance and the Memorial Day weekend.
