A father and son were shot and killed in McFarland Tuesday night and the suspects remained at large Wednesday.

The coroner's office identified the men as 28-year-old Fernando Valdez Jr. and 53-year-old Fernando Valdez Sr.

Valdez Jr. was shot at 11:05 p.m. in the 31000 block of Sherwood Avenue in McFarland. He later died at Delano Regional Medical Center.

Valdez Sr. was shot at the same time and died at 4:09 a.m. Wednesday at Kern Medical Center.

Sheriff's spokesman Ray Pruitt said no suspects have been identified and the motive remained unknown.

The shootings occurred at a ranch house surrounded by a white wooden fence, a large dirt field to the east and grape vineyards to the west. There was no answer at several houses across the street from the Valdez home.

A red SUV was blocking the driveway Wednesday morning, and crime scene tape was roped over gaps in the fence for the driveway entrance and exit. At least three pickups and two cars were parked on the property, which included a detached garage and a smaller building next to it.
