Police with cadaver dogs searched part of Hines Park in Livonia for Danielle Stislicki or for clues to her disappearance.
The Farmington Hills woman has been missing since last December.
Local police were joined by the FBI in the area of Hines Drive and Newburg Road.
Floyd Galloway Jr. was named a person of interest in her disappearance. He has been arraigned in a separate case involving an attack on a Livonia jogger near the area being searched.
Galloway worked as a guard at the building where Stislicki worked in Southfield.
Stislicki was last seen on December 2 after leaving work. Her car was found outside of her residence at Independence Green Apartments in Farmington Hills on December 3.
Police say the site is a natural place for them to search. They say 14 dogs were used in the search.
