Elias Wolford, a 5-year-old boy injured in a school shooting in Northern California, may not regain the use of his legs due to damage to his spinal cord from a bullet, according to a family update on a fundraising campaign page.

Elias Wolford, 5, and his kindergarten classmate Roman Mendez, 6, were shot by a gunman during recess at Feather River Adventist School on Dec. 4.

One of the kindergartners shot last week at a Seventh-Day Adventist school in Northern California hasn't been able to move his legs, his grandmother wrote on Facebook.

The two kindergarten students who were wounded in a school shooting in the Northern California community of Palermo remain in critical condition after a successful surgery on Friday, the Butte County Sheriff's Office said.

Two boys, aged 5 and 6, are in "extremely critical condition" after a shooting at a Christian K-8 school in California on Wednesday, authorities said. The gunman was found dead near the playground.

Mendez and Wolford were two of only 37 students in the faith-based K-8 school, associated with the Oroville Seventh-Day Adventist Church.

Glenn Litton shot two kindergarteners earlier this month in an attack he claims was revenge for the Gaza "genocide." His 5-year-old victim may lose complete use of his legs, his family said.
