PHOENIX -- A man accused in a South Phoenix serial rapist case has pleaded guilty to six charges.
Dejuan Donaldson, 20, pleaded guilty to two counts of sexual conduct with a minor, two counts of attempted sexual conduct with a minor, sexual assault and attempted sexual assault.
Donaldson was arrested in 2011 after police said DNA evidence linked him to the sexual assaults of three girls.

Two girls, ages 10 and 12, were sexually assaulted in attacks on November 2010 and January 2011.
The three attacks occurred while the girls were walking to or from school.
Sentencing is set for Feb. 22.
