A Michigan State Police (MSP) forensics expert has been sacked for testing her husband's underpants for DNA evidence that he was cheating on her, the Detroit News reports.

Ann Chamberlain, 33, was given her marching orders on Tuesday following an internal MSP investigation "into violations of department administrative policy". She'd previously been suspended from her post after admitting to a divorce hearing in Ingham County Circuit Court's Family Division in March that she had "tested the underwear of her husband, Charles Gordon, in September 2006 for evidence that he had cheated on her".

At a later family court hearing in May, Chamberlain elaborated that she "ran the DNA tests on her husband's underwear using expired chemical agents that were going to be thrown away by the department".

Gordon and Chamberlain, who have one child, were finally divorced in July. The former's attorney, Michael Maddaloni, described the latter as "a dangerous woman", and insisted "law enforcement officials should be looking into prior cases that Chamberlain investigated".

Chamberlain had "given expert testimony in several high-profile cases, including the death of seven-year-old Ricky Holland and the 2005 murder of Lansing Community College professor Carolyn Kronenberg", the Detroit News notes. ®
