A 19-year-old Tucson man will be spending the next 10 to 22 years in prison after pleading guilty Wednesday to second-degree murder.
Vicente Salazar III admitted he caused the death of William Michael Flores, 28, on Feb. 27, 2011.
Pima County Superior Court Judge Howard Fell will sentence Salazar Aug. 17.
Salazar and an unknown person decided to rob Flores because they believed he was selling crack cocaine in their gang area, according to court documents. Salazar knocked Flores off his bicycle by hitting him in the head with a 12-gauge shotgun and shot him in the back as Flores tried to run away.
Flores died in the alley between East 30th and 31st streets, near South Fourth Avenue.
Witnesses identified Salazar as the shooter, Salazar confessed and the murder weapon was found at his house, court documents state.
