MINNEAPOLIS  -- A 57-year-old Minnesota man released from prison after serving about 10 years for a murder he says he did not commit says being free is "wonderful."

Terry Olson was released from Faribault Correctional Facility Tuesday. Olson received credit for time served, but did not receive a legal declaration that he did not commit murder.

Olson was convicted in 2007 in Wright County of killing Jeff Hammill. Hammill's body was found on a road outside of Buffalo in 1979.

The Innocence Project of Minnesota fought for Olson's release. He faced seven more years in prison.

In an interview, Olson said he's "innocent of a crime that in all likelihood never occurred. "

But Wright County Attorney Tom Kelly continues to believe Olson was guilty of killing Hammill.
