Authorities in Tennessee issued an Amber Alert on Tuesday for a missing 3-year-old boy after his case was upgraded by investigators. 

Noah Clare was last seen Nov. 6 and officials believe he could be with his father, Jacob Clare, 35, who is also being sought. The Subaru Legacy authorities believe the elder Clare was driving was found in San Clemente, California, a coastal community between San Diego and Los Angeles, the Tennessee Bureau of Investigation said Tuesday night.

Jacob Clare faces a charge of especially aggravated kidnapping, the TBI said. He is also wanted for custodial interference and kidnapping by local authorities in Tennessee and Kentucky.

Investigators believe the elder Clare left Kentucky with his son and 16-year-old niece, Amber Clare, to drop off his son in the Nashville suburb of Gallatin. 

Clare is 6-foot-7, weighs about 200 pounds and has a tribal tattoo on his arm, authorities said.

He was last seen driving the Subaru Legacy with his son and niece. The vehicle no longer has stickers on the back, authorities said. 

Investigators said the vehicle was last seen in Arizona last week. Authorities there have issued an Amber Alert as well, the TBI said. 

Images of the discovered vehicle showed scratches and dents on the outside and a mix of clothes, blankets, and other items littered on the inside, including MREs – Meals Ready-to-Eat --which are mostly consumed by military personnel during training. 

Authorities did not say if the missing children were found but noted that they have requested assistance from California law enforcement on the case.
