DETROIT -

Former Detroit Police Department lieutenant Bill Rice and co-defendant Cheryl Sanford pleaded guilty to continuing criminal enterprise and perjury charges on Friday before Judge Gregory Bill.

Rice was charged with perjury for testimony in a quadruple murder case.

Prosecutors say Rice testified in a 2009 evidentiary hearing as a defense alibi witness. Davontae Sanford had been charged in 2007 in the slayings of four people when he was 14 years old. Sanford pleaded guilty, but his lawyer sought to withdraw the plea.

The state Appeals Court sent the case back to the lower court where Rice testified.

Moreover, both Rice and Cheryl Sanford, Davontae Sanford's aunt, were charged last year with conducting a criminal enterprise.

On Friday, Rice pleaded guilty to two counts of perjury and one count of continuing criminal enterprise. He could be sentenced between 2-20 years in prison. He also must pay restitution of $100,196.

Cheryl Sanford pleaded guilty to one count of continuing criminal enterprise and one count of false pretenses. She likely will be sentenced to 5 years of probation with the first year to be spent in the Wayne County Jail. She also owes $100,196 in restitution.

Their sentencing date is scheduled for Jan. 29.
