"We understand the allegations are very serious," defense attorney Frank Manley told The Flint Journal. "Obviously, we are in the initial portion of our investigation, but we expect to have a successful outcome."
A hearing to determine if there's probable cause to send Woods to trial is set for Oct. 2. If convicted, the mandatory minimum sentence would be 25 years in prison.
The Journal reported that Woods joined the Flint department in 1975, although the year of his retirement was not immediately known. He was honored by a homeowners association in 1986 for capturing burglary suspects while working as a part-time security guard.
