The skeletal remains of 27-year-old Corrie Renee Ottenbreit, a prostitute from Edmonton, Canada, reported missing in 2004, have been identified by the Royal Canadian Mounted Police. The finding marks the fourth in a string of remains found within an 8-kilometer radius of the area since 2003, reported the Edmonton Journal.

The RCMP are currently looking into the connection between these four cases, and the possibility of the suspect being a serial predator.

"Obviously, with the proximity of these deaths, it is a possibility," said Insp. Stacey Talbot of the Alberta RCMP's Serious Crimes Branch. "It could be one person committing these offenses on a number of different individuals."

Two of the three other victims, Katie Ballantyne, 40, and Delores Brower, 33, were also prostitutes.

This is not the first time the RCMP investigated the possibility of serial killers being connected to the disappearance of Edmonton-area prostitutes — they conducted a similar investigation back in 2007.

Ottenbreit was identified using DNA analysis techniques on a sample of her hair she provided to the Project KARE task force in 2003.

Her family members released a statement in which they remembered her as a loving daughter, sister and friend that they will continue to hold in their memories, reported the Globe and Mail.
