WOONSOCKET - Tuesday marked the five-year anniversary of the disappearance of a Woonsocket woman, and South Dakota law enforcement leaders say they are continuing to work the case.

Rachel Cyriacks, age 30 at the time of her disappearance, went missing Nov. 13, 2013. A news release from South Dakota Attorney General Marty Jackley Tuesday noted the anniversary, and stated that tips and assistance in the case are still being sought.

"State and local law enforcement continue to receive tips and are actively following up on leads in Rachel's case," Jackley said in a statement. "We ask the public to continue to be vigilant and aware of their surroundings. Anyone who believes they have information is asked to contact law enforcement."

Officials have previously suspected foul play in the incident and don't believe Cyriacks will be found alive. Since her disappearance, law enforcement has searched various sites, including private scrap yards, ditches, farmland and public hunting areas looking for signs or leads regarding Cyriacks. In 2015, authorities released a photo of a quilt Cyriacks owned to see if it would lead to any possible tips.

Cyriacks was last seen driving a 1995 Chevrolet Silverado pickup truck that is gray, with the South Dakota license plates 4CH 634. She was seen in Woonsocket and Mitchell on Nov. 13, 2013. The pickup was recovered in early January 2014 with significant damage to the vehicle's undercarriage.

On a missing person poster released again Tuesday, authorities said Cyriacks frequented the Huron, Mitchell and Sioux Falls areas.

Cyriacks is described as a white woman, 5-foot-5, 140 pounds, with blonde/brown hair and hazel eyes. She has numerous tattoos, including on her right forearm and left side of her neck.

Information about the disappearance can be relayed to the Sanborn County Sheriff's Office at 605-796-4511.
