Agoura Man Slain at Excavation Firm : Moorpark: Two men are seen fleeing after the victim is shot to death near the California 118-23 connector project.

An Agoura man was shot and killed Saturday as he worked at a Moorpark excavation company, authorities said.

Raul Castillo Nunez, 44, was attacked at about 8:20 a.m. by two gun-wielding assailants at Salas Excavation Co., a dirt-removal business near the new California 118-23 freeway connector, Ventura County Sheriff’s Sgt. Pat Buckley said.

Nunez, who suffered multiple gunshot wounds, was discovered moments after the shooting by employees of Conejo Ready Mix, a cement-making business, Buckley said. The Salas Excavation Co. leases a small dirt yard on the grounds of Conejo Ready Mix, located on Los Angeles Avenue near Spring Road.

Nunez, a mechanic for the excavation company, was working alone in the yard, deputies said. His body was found between a tool shed and a chain-link fence.

Deputies believe a shotgun was used in the slaying, Buckley said.

However, several people within earshot of the shooting said the gunfire sounded more like shots from a handgun.

“Bang! Bang! Bang!--rapid fire-like,” said Merv Miller, owner of APCO Supply, an irrigation materials supply business located about 50 yards west of the shooting site. Miller and another APCO employee said they saw two men fleeing.

Steve Davis, a dispatcher with Conejo Ready Mix, was among the employees who found the body.

“I went over and looked at the body. He had a bullet in the middle of his forehead and (was) bleeding from the abdomen,” Davis said.

Moorpark sheriff’s deputies pronounced Nunez dead at the scene.

A man at the excavation site who identified himself as a cousin of Nunez’s said family members believe the killing stemmed from a fight with other family members, but would not elaborate.

“We’re 90% sure who did it,” said the man, who declined to give his name.

About 15 family members, including Nunez’s son, flocked to the site after the slaying. The son, also an employee of Salas Excavation, was not present when his father was killed, deputies said.

Darrel Clubb, a cement truck driver, said he was in the yard at the time of the shooting and saw two men run out the front entrance of Conejo Ready Mix. Both men jumped into a white Chevrolet pickup truck parked at the main gate and sped away eastbound on Los Angeles Avenue, he said.

A Sheriff’s Department helicopter was summoned to search for the truck, authorities said.

Clubb said he was asked to ride in the helicopter to help identify the vehicle.

“They flew us to two sites, Santa Paula and Simi Valley, looking for the white truck,” Clubb said. The aerial search was unsuccessful, he said.

An investigation was continuing late Saturday.
