MILWAUKEE (WRN) - More troubles emerge for the Milwaukee County Sheriff's Office when it comes to collecting DNA samples. A problem revealed last October was evidently much worse than originally thought. Now, the office is admitting it failed to collect samples from 561 inmates. That's about 200 more than Sheriff David Clarke Junior disclosed earlier. The department says it is still looking for 180 of those inmates at this time. Two months ago the department said all the inmates who hadn't been sampled were in custody. At the time the story first came out, the sheriff announced that a captain and two sergeants had been suspended in connection with the failure.
