Despite all the podcasts, shows, and books about the Ted Bundys and Zodiac Killers of the world, serial killers in general are quite rare. In fact, serial murder makes up less than 1 percent of homicides in the United States, according to the FBI.
But against all odds, one city was terrorized by multiple different serial killers at the same time.
As shown in an upcoming episode of the new season of "Mark Of A Serial Killer," airing Sundays at 7/6c on Oxygen, the summer of 2006 was a deadly one for Phoenix, Arizona. A shadowy figure known as The Serial Shooter was sniping people from their car. Another murderer, nicknamed The Baseline Killer, was taking women off the road, sexually assaulting them, and murdering them if they didn't comply. He got his name because he initially hunted victims near Baseline Road, The Arizona Republic reported in 2016.
Here's what to know before the episode airs.
The Serial Shooters
The Serial Shooter was eventually found to be two men: Dale Hausner and Sam Dieteman. From late 2005 to July 30, 2006, the pair committed drive-by shootings together. By the end of their spree, they had murdered at least eight people and wounded another 18, NBC 12 reported in 2021. They also set items on fire, store things, and killed animals during their disturbing crime spree.
Why did they do it? Hausner was the ringmaster, Dieteman claimed. The two men were bored and high on meth and considered the violence a fun activity to pass the time, according to The Arizona Republic.
The two men were caught after Dieteman told a friend he had participated in some of the shootings. That friend went to police, and they eventually linked Dieteman to an old friend, Jeff Hausner, who participated in some of the shootings, and his brother, Dale Hausner, according to NBC 12. They ended up wiretapping the apartment and heard the two bragging about the shooting spree.
"I love shooting people in the back. That's so much fun. That [expletive] old man I shot in the back," Dale Hausner said at one point in the conversation, The Arizona Republic reported.
The two were arrested on August 3, 2006. Dale Hausner refused to speak, but Dieteman confessed all to police. Dieteman was sentenced to life in prison without the possibility of parole, while Dale Hausner was sentenced to death. He died by suicide in 2013, according to NBC 12.
Jeff Hausner was sentenced to 25 years in prison for his role in the shooting spree.
The Baseline Killer
But while two killers were caught, authorities knew they had a serial rapist and murderer on the loose.
Phoenix Detective Clark Schwartzkopf told The Arizona Republic, “You couldn’t have two more different dynamics in these two murderers, but the public was mixed up.”
From August 2005 to June 2006, a man was taking women by force off the street, often during the daytime hours, adding to the fear and chaos he was causing. He would rape the women, and shoot them in the head if they didn't comply.
Ultimately, he attacked 33 people and killed nine, according to The Arizona Republic.
The murderer was caught in September 2006 and unveiled as Mark Goudeau. Goudeau was a married man, well-liked by his neighbors, a construction worker. But he had a past history of sexual assaults and criminal activity, and due to his proximity to some of the attacks, was already considered a suspect, the outlet reported.
After attacking two sisters, one of whom was six months pregnant, he was caught. DNA evidence was able to be recovered from one of the women, and it led to Goudeau. When they searched his home, they found mementos connecting him to the other victims.
He was sentenced to death in 2011.
