For more than a year, Mark Goudeau terrorized the Valley. He left nine dead, raping and robbing many more, before ending up on death row.
Now some are wondering if he could have been stopped.
Goudeau, known as the "Baseline Killer", began his crime spree in August 2006, sending a chill through the desert air and leaving a trail of fear across the Valley.
His vicious crime spree lasted until September 6, 2006 when he was arrested at his central Phoenix home on his 42nd birthday.
One Valley attorney says he has the proof Goudeau could have been captured long before his spree was finally over.
"They just simply dropped the ball, there were actually eight people murdered during that time frame that would not have been murdered had Mark Goudeau simply been taken into custody," said the attorney, who now represents five of the victims' families.
The families are suing the City of Phoenix, claiming DNA evidence that could have stopped Goudeau wasn't tested.
"Had the Phoenix crime lab just tested it 11 months earlier, Mark Goudeau is off the street and these murders don't happen," said the attorney.
Goudeau's victims, as young as 12-years old, struggled to identify the criminal, while others were silenced by gunshots to the head.
Goudeau was eventually convicted, sentenced to 438 years in prison for sexually assaulting two sisters in a south Phoenix park.
The attack on the sisters took place on September 20, 2005.
DNA linked Goudeau to the attack on the sisters.
It's that DNA and how it was processed that's now at the center of the lawsuit.
ABC15's Christopher Sign is sitting down with the attorney and the victims' families for a special investigation Monday on ABC15 News at 10.
