CHINO HILLS >> The San Bernardino County District Attorneys office announced Thursday it would not prosecute anyone involved in the Oct. 4, 2012, shooting that sent two young men to the hospital following an apparent road rage incident involving an off-duty Huntington Park police officer at the Shoppes Center.

Due to insufficient evidence to prove guilt beyond a reasonable doubt, charges will not be filed against any of the involved parties at this time, DA spokesman Christopher Lee said. As a result of pending civil litigation, we are unable to comment any further.

Brian Sloma, Addison Weeks, Kenneth Chan and Eugene Lee were driving on the 71 Freeway when off-duty Huntington Park police officer Ricardo Curiel allegedly began tailgating the four.

Sloma claims in court documents he tapped his brakes to get Curiel to back away, but that action allegedly enraged the off-duty officer.

Court records say Curiel allegedly became more aggressive and was tailgating the four in a dangerous and unsafe manner.

Sloma again tapped on his brakes which finally forced Curiel to distance his car from theirs, according to the civil complaint filed July 17 in Los Angelels Federal Court in Los Angeles.

Sloma drove the car into the parking lots of the Shoppes shopping center and after circling the parking lot being closely followed by Curiel, he pulled his car in a parking stall, according to reports.

Curiel pulled up behind the car in a felony stop formation, according to the complaint. Thats when shots were fired.

Authorities said the shooting was sparked by road rage but did not say who detectives believed was the aggressor or provide details of the incident.

Weeks, Sloma and Chan were arrested after the San Bernardino County sheriffs investigation.

In the complaint attorneys for the three say the men named in the suit are responsible for the injuries, trauma, intentional infliction of emotional distress following the road rage-inspired shooting.

Attorneys also claim the civil rights of Weeks, Sloma and Chan were violated by the city of Huntington Park, Huntington Park Police and Police Chief Jorge Cisneros, San Bernardino County, former San Bernardino County Sheriff Rod Hoops, unnamed deputies of the San Bernardino County Sheriffs Department and Huntington Park Police Officer Ricardo S. Curiel.

Following the shooting, deputies found an 8-inch knife and a can of pepper spray within the crime scene area outside one of the cars.

Curiel reportedly fired several shots. It was unclear if he ever identified himself as an off-duty officer prior to firing.

The complaint said Weeks and Sloma were struck multiple times as they ran away from Curiel.

Huntington Park Police and Officer Curiel could not be reached for comment on the pending lawsuit or DAs decision not to prosecute anyone.
