Around 6.40am on Feburary 19, a United States Border Patrol agent shot and killed Jesus Flores Cruz, a 41-year-old Mexican national, four miles east of the Otay Mesa port of entry to the US in southern San Diego. Employing what has become an all-too-familiar explanation, authorities said Flores Cruz, an unauthorised migrant, pelted the agent with rocks. Reportedly fearing for his well-being, the agent shot his pistol twice, fatally wounding the alleged attacker.
