Police say the woman either jumped, fell, or was pushed from the sixth floor of the garage on Wednesday.
A silver, four door Saturn was seen leaving the garage at the time of the incident.
A short time later, police arrested a person of interest, Eric Stucker, on unrelated charges. Stucker was arrested in January after police say he tried to rob the Circle K on First Avenue. Police have not said why they want to question him in this case.
An autopsy on the woman is scheduled for later today.
