A Mexican man accused in the hit-and-run death of a Phoenix doctor has pleaded not guilty.
Maricopa County Superior Court officials say 26-year-old Ruben Santiago-Lopez entered his plea Thursday to a charge of leaving the scene of a fatal accident.
Santiago-Lopez was arrested last week after he turned himself in at the Nogales port of entry.
Police say Dr. Robert Arceci died at the scene after a landscape truck turned in front of him while he was riding his motorcycle in Scottsdale in June 2015.
The 65-year-old Arceci was hematology/oncology division chief at Phoenix Children's Hospital.
Police say the truck that hit Arceci pulled over and remained on scene with two occupants, but the driver identified as Santiago-Lopez ran away and fled to Mexico.
His next court date is Jan. 3.
