A pickup truck hit a pedestrian in a Mira Mesa intersection Wednesday, leaving her gravely injured, authorities reported.

The unidentified woman, believed to be in her 60s, was crossing Camino Ruiz at Westmore Road in a crosswalk when the 2015 Toyota Tacoma struck her at about 7 a.m. Wednesday, according to the San Diego Police Department.

Paramedics took the victim to a hospital for treatment of extensive trauma, including a serious brain injury and fractures to her skull, ribs and pelvis.

“She is not expected to survive her injuries,” SDPD Officer Sarah Foster said.

Intoxication was not believed to have been a factor in the accident, according to police.
