Donald William Tobin, 52, was last seen on July 7, 2010, in Riverside, California. He left his home on Redwood Drive to put items into a storage unit and never returned. On July 11 his silver 2007 Toyota Corolla was found abandoned at Carlson Dog Park, less than a mile from his home, with the items he planned to store still inside the car along with his wallet and cell phone.

Extensive searches around Carlson Dog Park, including helicopters and search dogs, turned up no trace of Tobin. He did not access bank accounts or collect his last paycheck. His family does not believe he disappeared voluntarily or died by suicide and suspects foul play. Investigators have been unable to determine the cause of his disappearance and the case remains unsolved.

Did anyone see Donald near Carlson Dog Park in early July 2010 or notice anything unusual that week?
