SAN DIEGO (KGTV) - The husband of a San Diego woman has turned to social media to find his wife, who he believes she may have been carjacked or kidnapped.

Jonathan Chappell said he last spoke to his wife, 40-year-old Crystal Chappell, on Sunday before she drove to Mission Valley to pick up their two children from church.

However, Chappell said his wife never showed up. He called her several times, but she never answered.

Chappell told 10News he then tracked his wife's cell phone and it pinged near southbound Interstate 805 towards Mexico. He's concerned his wife may have been carjacked or kidnapped.

Chappell and a family friend searched the area, but they found nothing but bushes and a homeless encampment.

Chappell told 10News his wife's medical needs have him worrying even more.

"She has obstructive sleep apnea, which means when she sleeps she stops breathing in the middle of the night. She has a BiPAP machine with oxygen; she's supposed to have her oxygen at night as well. She doesn't have any of that with her," Chappell said.

Crystal Chappell is 5 feet 1 inch tall, weighs 336 pounds and has dark brown hair and brown eyes. She was last seen wearing a pink and black striped shirt, pink and black plaid leggings, and blue tennis shoes with teal soles.

She has a rose tattoo on her left breast and is missing a tooth on the left side of her mouth.

She was driving a 2001 Mercury Cougar with California license plate number DP122NW.

10News learned police have a missing persons case filed.

Anyone with information is asked to call Jonathan Chappell's cell phone at (619) 886-2393 or his home phone at (619) 264-1736.
