The vehicle belonging to a Kentucky man accused of kidnapping his 3-year-old son and 16-year-old niece has been located in California, according to local law enforcement.

The Beaver Dam Police Department in Kentucky and Gallatin Police Department in Tennessee are searching for Jacob Clare, 35, whom they believe may have Noah Clare of Tennessee and Amber Clare of Kentucky in his custody.

The Beaver Dam Police Department labeled Amber as an endangered missing person on Nov. 14. The Gallatin Police Department updated Noah Clare's missing status to endangered missing child last week.

Clare was apparently en route to drop off his son with family after he picked up Amber, but no one has heard from them since. The family believes Jacob picked up Amber the morning of Nov. 6.

"I’m sad, I’m angry, I’M FREAKING PISSED THE F*** OFF!!! IT SHOULD NOT BE LIKE THIS!!!! The whole time we have been begging for an amber alert, Jake was able to drive Noah and Amber all the way to freaking California. The car has now been found, abandoned 6 days ago, and now we have no idea where they could be," she wrote.

Ennis continued: "If they released the amber alert when we asked 10 days ago, MY BABY WOULD BE HOME!!! It is absolutely ridiculous. Please continue sharing with EVERYONE you know. Specially out west. Please, help me find my Noah and pray that he is still happy, healthy, and safe."
