(Note: I'm not sure if Sandra's correct surname is McCarthy or McCarty. The original PD alerts gave the spelling as McCarthy, but now some LE reports are spelling it McCarty, and some are using both spellings in the same report. Both of the articles I am linking in this post give the name as McCarty. The 2nd linked article gives Sandra's father's name as Robert McCarty. I wasn't able to find confirmation in public records.)
Info from the following article/video:
Whisper and Sandra were in Fresno for a medical appointment and to visit Whisper's mother and brother.
They left Fresno around 5pm on Tuesday to return to Elk Grove, where they live with Whisper's partner and their other two children.
The partner called Whisper's mother Saturday morning and asked to talk to her. That was when they realized she was missing.
Whisper doesn't have a working phone, so her mom usually only talks to her every few days.
The car was last seen just before 8pm on Tuesday on a traffic camera near Shaffer & Bellevue in Atwater. Atwater is about 65 miles north of Fresno.
Her family says that Whisper has a medical condition that could have caused an emergency.
The family has been conducting their own search along SR-99.
Whisper's brother says that she would normally take 99 to Grant Line Rd to Elk Grove.
An urgent search is underway for a missing mother and her baby, stretching from Fresno all the way up to Sacramento.

Car seen on surveillance camera in Atwater. Previous damage to front driver's side.
"Close friend Tiffaney Machado says the SUV was spotted heading south near Shaffer and Bellevue at 7:27 p.m., then northbound in the same area at 8:12 p.m."
Owen was supposed to return to her home in Elk Grove where her partner, Robert McCarty, and her two other children were waiting.
McCarty says it’s not unusual for her to spend a few days visiting family in Fresno, which is why no one initially suspected anything was wrong.
Friends describe Owen as a loving, attentive mother, and say her disappearance is completely out of character.
Her family said she left the city around 5 p.m. on July 15.
