The Tetris Murders

Police find a Russian family brutally murdered in a Silicon Valley home, a co-developer of the video game Tetris among them. But something doesn't sit right with detectives, and it has to do with evidence -- or, more importantly, the lack of it.

Detectives investigating the bizarre apparent murder-suicide of a Russian man and his family are puzzled by inconsistencies in the evidence. But as they start to suspect this may be a staged scene, a surprising source thwarts their investigation.

Determined to prove that Tetris co-developer Vladimir Pokhilko did not kill himself and his family, retired Palo Alto PD crime scene investigator Sandra Brown returns to the crime scene and uncovers more jaw-dropping discoveries.
