On Dec. 9, 27-year-old Jelinek of Oakdale was reported missing by family members.
Her on-again/off-again boyfriend, 28-year-old Aaron Schnagl, claims to have spent the evening with Jelinek and told police she left his home in Chisago Lake Township on foot the same day she was reported missing.
Many of her belongings including her car, purse, shoes and cell phone were found at Schnagle's home.
Schnagl is currently being held in the Anoka County Jail for a probation violation.
His attorney, Rachael Goldberger, told KSTP that no evidence links Schnagl to Jelinek's disappearance. He has not been charged in the case.
"He's not capable of hurting somebody," Theresa Langevin, Schnagl's cousin, tells the television station.
Authorities say they continue to follow leads that come into their office on a daily basis.
