""Nothing a new city can't cure." - Matt Chambers, to Dexter"
Matthew "Matt" Chambers (also known as Matt Brewster and Matt Rasmussen) was a Character in DEXTER. He appeared as a repeat-drunk driver that used his emotional reactions and fabricated stories to escape conviction with multiple accidents caused by his drunk driving. To keep up appearances, he changed his name and often the city after each incident but unfortunately passes into Dexter Morgan's sights...where he becomes Dexter's Third Shown Victim.
Matt was an alcoholic and repeated drunk driver who had killed 2 people and injured one. He manages to avoid any significant punishment by putting on a sad face in court, crying crocodile tears and lying about his car being stolen. However, even after being exonerated, he would change his name and move to a new city. Though not explicitly stated, it appears Chambers isn't purposefully targeting his victims, but has a complete disregard for their lives.
He injured a woman in Santa Fe, killed an off-duty firefighter in South Boston, and finally killed young man named Alexander Prycein Miami Florida.
After Chambers is found not guilty for a third time, Dexter follows him to a local bar, where he finds him drinking again. Dexter soon captures and kills him in an abandoned convenience store, with a stab to the chest.
