Prison Instructor Emerges as Central Figure in Escape Probe

In the months before two convicted killers escaped, prison tailor-shop instructor Joyce Mitchell was investigated over a possible relationship with one of the men. Authorities say the 51-year-old woman has become a central figure in the escape probe. Mitchell is suspected of aiding the breakout by supplying the two inmates with prohibited items, and agreeing at one point to be the getaway driver. District Attorney Andrew Wylie said Friday he is considering charges against her.
