Hector Alvarez, 41, was last seen on July 28, 2009, at the Milpitas home where he was staying with his sister. He left that day without telling anyone and did not take personal belongings, including his cell phone. In the weeks before he disappeared, Alvarez had been using the family computer to research suicide methods, a detail that raised concerns about his state of mind.

Alvarez is described as a Hispanic male, 5 feet 7 inches tall, 110–120 pounds, with black hair, brown eyes and two distinctive moles on the right side of his face. There have been no confirmed sightings or leads since July 28, 2009, and the Milpitas Police Department continues to seek information.

If anyone knew Hector, saw him around Milpitas in late July 2009, or has information about his whereabouts, please share what is known with the Milpitas Police Department.
