The Allegheny County District Attorney's office filed a motion today seeking to collect a DNA sample from the University of Pittsburgh researcher accused of killing his wife with cyanide last year.
Robert Ferrante, 65, is charged with poisoning his wife, Autumn Klein, in April.
According to the motion filed by assistant district attorney Lisa Pellegrini, evidence collected by the Pittsburgh police mobile crime unit is suitable for DNA analysis, but none has yet been collected from Mr. Ferrante. The prosecution is seeking permission to conduct a buccal -- or cheek -- swab.
A pretrial hearing in the case is scheduled before Allegheny County Common Pleas Judge Jeffrey A. Manning for Feb. 10.
