Stockton Police say Richard Alcaraz was hiding out with family in Cabo San Lucas. U.S. Marshals, working with Mexican police, arrested the 22-year-old.
The suspect wanted in the deadly shooting of a Stockton store owner was arrested in Mexico and extradited back to the U.S. on Wednesday.
The Stockton Police Department has identified one of the suspects in a shooting last month where a store owner was killed.
