"Luke was last seen on the afternoon of March 8, 2025, at approximately 2:45 p.m., when he left his home near N. 126th Avenue and N. Westland Road. It is believed he drove to go hiking a few miles from his residence. His vehicle was later found a few miles west of his home, near a desert area," the Peoria Police Department said.

What they're saying:
Peoria PD says his family is extremely concerned about him and have been actively searching for him. He does not have a cognitive disability, but investigators say given statements he made prior to leaving, it gave cause for concern.
His cell phone appears to be turned off.
On March 10, the police department detailed all the efforts it has made to find Wuennenberg, calling it a "large-scale operation."
The department has used the Phoenix Firebird helicopter for aerial search assistance, Maricopa County Sheriff’s Office Search and Rescue mounted unit, and the Arizona Department of Corrections, Rehabilitation and Reentry's bloodhounds.
Officers have also conducted extensive ground searches.
"At this point, our search efforts have been exhausted and we ask for the help of the public should someone see or hear something regarding Luke," police said.
