Update (Jan. 21, 2025) —  Shuefuab "Shue" Xiong died by suicide outside a St. Paul residence, according to police. 

MINNEAPOLIS — The car of a missing 42-year-old Apple Valley pizza delivery driver has been found in Wisconsin, police say.

A witness told authorities they believe they saw Shuefuab "Shue" Xiong in the red Toyota Camry in Superior around 4 p.m. Saturday.

The Camry was found, unoccupied, by police in Superior on Sunday. Superior is around 170 miles north of Apple Valley. 

Police also say a friend of Xiong spoke to him in Roseville Saturday around 8 p.m. It's unknown how he traveled from Superior to Roseville. 

Investigators believe Xiong may be having a mental health crisis. He is not believed to be a threat to others, but authorities say he is known to carry a firearm and has a permit to carry.

Xiong reported to work at Domino's in Apple Valley on Jan. 14 but didn't make four scheduled deliveries.

He is described as 5 feet 8 inches tall and 215 pounds. He is bald and has a black mustache, black beard and brown eyes, the Minnesota Bureau of Criminal Apprehension says.  

"Our family remains deeply concerned for Mr. Xiong's safety and well-being," his family said in a written statement Monday. "Thank you for your continued support, thoughts, and prayers during this difficult time as we work to bring him home safely."

His family is offering a $20,000 reward for his safe return.
