Armstrong was last seen by his girlfriend as she left for work at 7:45 a.m. His brother stopped by to check on him an hour later and found the house empty. The missing man’s wallet was still there. That day, Armstrong also failed to keep a lunch date with his girlfriend.

He is missing along with Steven Lombard (NamUs # 19503). Both men worked at the same business as tow truck drivers, in Merced, California. Lombard's truck was found abandoned in a local business parking lot, unlocked, with the keys inside and the windows rolled down. Neither have been seen again.
