LANSING, Mich. (AP) – Officials say new DNA testing points to a different killer in a 1981 slaying for which a Michigan man is serving a life sentence.

Ingham County Circuit Court set a Sept. 23 hearing to consider new evidence that could overturn the conviction of 53-year-old Michael Darnell Harris in the slaying of 77-year-old Ula Curdy of Lansing reports The Detroit Free Press.

Interim Ingham Prosecutor Gretchen Whitmer says freedom for Harris anytime soon appears unlikely, given his record.

Harris’ court-appointed lawyer Edwar Zeineh says other convictions from what was seen as the work of a serial killer and rapist could fall.
