MISHICOT, Wis. -- Manitowoc County investigators will hold a news conference Tuesday morning to release the latest information on the search for Teresa Halbach.

Halbach, a freelance photographer, was last seen Oct. 31.

Her family spoke to reporters Monday. "We hope she will come home," said brother Mike Halbach. "At the same time we are preparing for the worst, but we don't know where she is. Until we know where she is, we definitely think she will come home to us."

Authorities are now concentrating their search at a salvage yard near Mishicot, just north of Manitowoc.

A police tip led investigators to the salvage yard Saturday, where they found Halbach's Toyota Rav4.

Ironically, the salvage yard is owned by Steven Avery's family.

Avery is a man who spent 18 years in prison for a sexual assault he didn't commit.

Police believe Avery may have been the last person to see Halbach alive.

Monday nearly 200 people searched the area around the salvage yard.

Avery said Halbach regularly came to the property to photograph vehicles for an auto trader magazine.

He said that's what she was doing Saturday at the salvage yard.

Investigators have executed a number of search warrants on the Avery property and the family's cabin in Marinette County.

Avery said he fears he is being set up as a suspect.

Avery is suing Manitowoc County for $36 million for the wrongful conviction. He believes the lawsuit is the reason behind the setup.

Monday reporters questioned Avery asking, "Do you have any idea how her (Halbach's) SUV ended up on your family's land?"

Avery replied, "You got me. I got a hunch Manitowoc County planted it."

Avery has not been named a suspect and no traces of foul play have been found.

The Manitowoc County prosecutor has assigned a special prosecutor from Calumet County to handle the case with regards to Avery to avoid a potential conflict of interest.

Avery remains at a family cabin north of Green Bay near Crivitz.

Authorities are not allowing him back on the salvage yard property.

Avery said he couldn't go there anyway because police seized two family vehicles and he is without transportation.
