Clinton County authorities are asking for help from members of the public who may have seen Alysia Kay Marburger prior to her disappearance around Oct. 10 and the discovery of her body near Camanche one week ago.
Marburger, 27, Sabula, was found dead around 11:08 a.m. Oct. 24 alongside an access road to Rock Creek Cabins, located at 2829 Hwy. 67, Camanche.
Clinton County sheriff Rick Lincoln told reporters Thursday investigators are treating the death as "suspicious."
"We're seeking the public's assistance so we can track down any leads," Lincoln said.
The state medical examiner's office has not yet released information on the cause or manner of Marburger's death. An employee at the medical examiner's office told The Observer an autopsy has been completed, and the office is waiting for test results from another laboratory before making its ruling.
County attorney Mike Wolf said the death is being treated as suspicious "due to the circumstances in which the body was found."
He declined to elaborate on the specifics of the circumstances and did not comment on questions about whether a sexual assault was involved or rumors Marburger may have been connected to a drug investigation.
"There are other details due to the ongoing investigation it would not be prudent to release," Wolf said.
Marburger was reported missing Oct. 10 in Jackson County. Investigators are particularly interested in speaking with anyone who saw Marburger or her car around the evening hours of Oct. 6 and the morning of Oct. 7.
She was last seen around those dates, Lincoln said.
Her vehicle, a 2002 four-door Hyundai Sonata, with a personalized University of Iowa license plate that reads "MISSLEO," is in the possession of law enforcement.
"It's a unique vehicle. People may have seen this car. If anyone has seen this vehicle, please report it," Wolf said.
Wolf asked the public not to jump to any conclusions about Marburger's death being categorized as suspicious.
"It's a way for law enforcement to deal with a death investigation and get as much information as possible," he said.
Wolf said there is no need for members of the public to be concerned about their safety.
Marburger lived with her parents and a 10-month old child at 608 River St., Sabula. She was a student at Clinton Community College.
Anyone with information regarding the whereabouts of Marburger or her car on Oct. 6 or Oct. 7 should contact the sheriff's office at (563) 242-9211. Calls can be made anonymously to Clinton County Crime Stoppers at (563) 242-6595 or 1-888-883-8015.
