WILMINGTON, N.C. — Defense attorneys want to delay a murder trial in North Carolina because they say a former police officer who collected evidence is involved in a state investigation.

The StarNews of Wilmington reports (http://bit.ly/2r63PpS ) lawyers for James Bradley say they need more time to investigate evidence processed by Wilmington police evidence technician Michele Mahamadou.

Bradley’s trial in the killing of 54-year-old Shannon Rippy Van Newkirk is set to begin Monday. She hasn’t been seen since April 2014 and her body has not been found.

Mahamadou was cleared of wrongdoing in a 2015 state investigation into mishandling of fingerprint cards. Wilmington Police say she resigned from the force on June 1.

Court records show Mahamadou collected a bloodstain that linked Bradley to a different killing.
