San Diego prosecutors on Monday dropped the criminal case against Sonoma County Supervisor Efren Carrillo stemming from his arrest in a Labor Day street fight.
A spokeswoman for the San Diego City Attorney's Office, which handled the misdemeanor case, said no charges would be filed "because there were conflicting accounts of what occurred and insufficient evidence to prove a case beyond a reasonable doubt."
The decision was made by a team of deputy city attorneys in the office's criminal division, spokeswoman Gina Coburn said.
The 2 p.m. announcement came a week before Carrillo's scheduled arraignment next Monday. He had faced the possibility of two misdemeanor charges: battery and disturbing the peace.
When Carrillo was arrested, he was booked on suspicion of battery causing serious injury, a felony. But police officials later deemed the case a misdemeanor.
The 31-year old Carrillo on Monday was in Keene near Bakersfield to attend President Barack Obama's declaration of a national monument at the home of Cesar Chavez, the United Farmworkers Union founder who died in 1993.
In response to a request for comment, he responded by text message Monday night, saying he was traveling, his cellphone was low on battery power and he would call by 8 p.m., but no call was received by then.
Carrillo, seen as a promising Latino politician with potential beyond Sonoma County, has refused for the past month to answer questions about the fight that left a man unconscious.
The San Diego prosecutors also dropped the case against another man arrested in the fight, identified by police as Rayan Jastaniyah, 22, of San Diego. He had faced a possible misdemeanor charge of disturbing the peace. City attorneys identified him by a different name, Ryan Astiniya Saelmj.
Carrillo and Jastaniyah were arrested at 2:10 a.m. on Labor Day outside a popular nightclub in San Diego's Gaslamp Quarter.
