The man accused of killing two Des Moines-area police officers last year has admitted to the shootings.

Scott Michael Greene, at a court hearing this morning , withdrew a not guilty plea submitted back in December. The 46-year-old Greene, who is from Urbandale,  then pleaded guilty to the November 2, 2016 ambush-style shooting deaths of Urbandale Police Officer Justin Martin and Des Moines Police Sergeant Tony Beminio.

A trial had been scheduled for this September in Dubuque County. Greene was sentenced today to life in prison.
