During the July Fourth weekend, five people, including two motorcyclists, have died in separate accidents in and near Ventura County.

The most recent fatality happened about 5:10 a.m. Saturday, when a pickup truck slammed into the back of a semi parked off Highway 126 near C Street in Fillmore.

One passenger, identified as Candalario Sanchez of Oxnard, around 20, was killed in the collision, according to a report from the Ventura County Sheriff's Department.

The occupants were trapped in the pickup truck, and it took emergency personnel nearly an hour to extricate them. Sanchez was pronounced dead at 6:27 a.m. at Ventura County Medical Center in Ventura.

An autopsy will be performed today, said Armando Chavez of the Ventura County Medical Examiner-Coroner's Office.

The unidentified driver, 24, is in the intensive care unit at Ventura County Medical Center. The Sheriff's Department is investigating the cause of the accident, the report said.

On Friday about 6:47 p.m., a fatality occurred in Simi Valley when a motorcyclist heading east on Los Angeles Avenue was struck by a vehicle as he turned left from Los Angeles Avenue onto Sinaloa Road.

The motorcyclist was identified as 68-year-old Walter Podulka of Simi Valley, said Deputy Medical Examiner Shasta Gainer. Podulka was treated at the scene but was pronounced dead at 7:12 p.m. at Simi Valley Hospital, according to a police report.

The other driver was 17, and because of his age his identity could not be released, said Lt. Dave Livingstone of the Simi Valley Police Department. The driver was not arrested.

Another accident was reported Friday at 2:37 p.m. on Grimes Canyon Road north of Moorpark.

A vehicle ran off the side of the road near Turfway Road, landing about 40 feet away on its roof, according to the California Highway Patrol.

Two of the vehicle's occupants, including a child, received only minor injuries, the CHP said, but a third person was killed. That person has not yet been identified.

Another accident was reported two minutes later, at 2:39 p.m. A car traveling south on Highway 101 near Lakeview Canyon Road and the Los Angeles County line went over on its side, according to the CHP.

A man inside the car died after receiving a serious head injury, the CHP said. He was identified as Juan Carlos Lopez, according to the Medical Examiner-Coroner's Office.

The fifth fatality happened in Moorpark about 1:55 p.m. Friday when a motorcyclist collided with an oncoming vehicle, according to the California Highway Patrol.

He was identified as 36-year-old Caleb Bryant of Moorpark, Gainer said.

Bryant lost control of his motorcycle while heading north on Stockton Road and crossed the divider into oncoming traffic, striking the other vehicle, according to the CHP.
