Perzov was last seen in San Jose, California on May 1, 2009. He sent a text message to Theresa Hanson, his girlfriend of eleven years, saying he would be stargazing on Mount Hamilton. He has never been heard from again. It's uncharacteristic of Perzov to leave without warning. He was driving his blue 1998 Audi with a fist-sized dent in the rear at the driver's side, and the license plates number 3VVN796. A photo of the car is posted below this case summary.

After his disappearance, Hanson checked Perzov's computer and discovered his financial records for the preceding three years were missing. She believes he was depressed over financial problems and possibly suicidal when he went missing, and she stated he carried a gun in the trunk of his Audi. An unopened bottle of Maker’s Mark and one drinking glass also disappeared from Perzov's home. Two weeks after Perzov was last seen, his vehicle was found abandoned at Big Basin State Park. Authorities also found an abandoned tent near the Sunset Trail. A letter from Perzov addressed to Hanson was inside it; Hanson characterized the letter as a suicide note. An extensive search of the park, which is 18,000 acres in size, turned up no sign of Perzov.

Perzov was born in Merrick, New York. He is Jewish, and his interests include hiking, camping, cooking, writing, aviation and stargazing. Police don't suspect foul play in Perzov's disappearance. His girlfriend remains hopeful that he's alive. His case remains unsolved.
