Aurora Police Department Destroys DNA Evidence

A Colorado police department is facing some tough questions today about why they destroyed evidence. It happened in Aurora.

DNA in nearly 50 sexual assault cases from 2009 was mistakenly destroyed. A detective found a DNA match in a 2009 case - but when he went to look at the rest of the case, the evidence was gone.

Yesterday the police chief publicly announced the errors and apologized. "Obviously this is not a good day for the department. We try our best to be transparent. When we make mistakes we come forward and acknowledge it and this is a very big mistake."

An expert panel will analyze what went wrong.

The panel will issue a public report with recommendations by November 1.
