A passenger of a pickup truck that crashed into a tree near Yokuts Park last week has died, according to the California Highway Patrol.

23ABC has not been able to confirm her age, but her son told 23ABC she was in her late 70's.

CHP says the driver, her husband, is still alive.

On April 2, the slow lane on southbound 99 was closed due to a crash that sent a pickup truck with a camper shell onto a tree near Yokuts Park.

According to CHP, the pickup truck driver hit the brakes suddenly and was rear ended by one of the two semis involved.

The victims had to be cut out of the vehicle by fire personnel. 

The driver is also in his 70's and was taken to a local hospital for major injuries.
