DENVER - Denver Police held a press conference on Friday afternoon to explain a DNA processing error that may have affected three criminal cases dating back to 2011.

According to police, they use a robotic DNA machine to analyze evidence. That machine has stopped functioning twice in the past few years - once in June 2011 and again in November 2013.

However, when the crime lab staff called the servicing company in 2013, some staff members realized the process given for restarting the machine in 2013 seemed to be different than the process given in 2011.

They started a quality control process which took about a month.

After that process concluded, it was concluded that the 2011 process was incorrect.

Ultimately, the 2011 process affected 24 DNA samples from 11 different cases. Only three of those 11 cases ever had criminal charges filed.

At this point, the District Attorney's Office and the City Attorney's Office will be informing the defendants involved in the three cases affected. It is unclear how this DNA error has or has not affected the three cases.

DPD says the reason they came forward on Friday was because they want to be transparent during this process.
