The Baseline Killer (or Baseline Rapist) was one of the two simultaneously occurring serial killer cases (the other being the "Serial Shooter") which terrorized the Phoenix metro area, between August 2005 and June 2006.

The crimes were referred to as the Baseline Killer since the first crimes began around Baseline Road in South Phoenix, Arizona. The crimes later spread north, primarily in the North Central area of Phoenix.

The Baseline Killer is believed to have committed nine counts of first degree murder (8 women, 1 man), in addition to 15 sexual assaults on women and young girls, 11 counts of kidnapping, and a number of armed robberies.[1]

Although not initially linked, the crimes were distinguished by having no apparent motive, and the murders were particularly brutal, with the killer often shooting the victims in the head. The criminal was often described wearing various disguises such as a Halloween mask as well as attempting to impersonate a homeless man or drug addict.

Police say that the shell casings found at each of the crime scenes all came from the same gun.[2]

Phoenix police spent thousands of hours patrolling and following up on hundreds of tips during the summer of 2006. As residents of Phoenix became increasingly alarmed by the random nature of the violent crimes, community meetings were called by the police to distribute a sketch based on the description given by the surviving victims. Frustration and fear blanketed the city as posters and billboards displayed the sketch of the Baseline Killer, offering a $100,000 reward for information leading to an arrest. It took the police over a year to finally come up with a viable suspect.

Mark Goudeau was at the time on Community Supervision (parole) with the Arizona Department of Corrections and supervised out of the Northeast Parole Office. In August 2006, Parole Officers in the Northeast Parole Office provided information to the Phoenix Police Department task force suggesting that Mark Goudeau matched the sketch of the Baseline Killer. Parole Officers searched Mark Goudeau's residence and found a ski mask and a realistic "toy" handgun. Police used this information to obtain a search warrant for Mark Goudeau's residence and found additional items that linked Mark Goudeau to crimes committed by the Baseline Killer.

On September 4, 2006, Mark Goudeau was arrested in connection to the sexual assault of two Phoenix sisters, an attack which was tied to the Baseline Killer investigation. The sisters, one of whom was visibly pregnant, were assaulted in a Phoenix city park on September 20, 2005. Goudeau was linked to the attack by DNA evidence collected shortly following the time of the crime.

On September 7, 2007, Goudeau was tried and convicted of all 19 charges relating to the attack on the two sisters. He was sentenced on December 14, 2007 to 438 years in prison for the sexual assault charges. Currently he is still awaiting trial for the 74 other criminal charges attributed to the Baseline Killer.

She was found dead from a gunshot to the head behind a barbershop about 100 yards (91 m) away. The attack was captured on closed-circuit television. This is the last crime attributed to the Baseline Killer.[5][6]


Phoenix police have released hundreds of pages of documents that detail their investigation into the Baseline Killer. The paperwork obtained by ABC15 News reveals that police have at least 10 names of possible suspects that they have looked into, and have ruled out some of those people. The 20,000 pages of police reports are primarily of other suspects with very little mention of Mark Goudeau. The documents reveal information on nine cases ranging from a double homicide to sexual assaults, robberies and kidnappings. The new information includes police reports and narratives that describe where and who police are looking at in the investigation. They also discuss investigative leads; however, much of the information was redacted.

According to the documents, the Baseline Killer posed as a homeless person in one incident, pushing a shopping cart toward a woman in a parking lot near 32nd Street and Thomas Road. He forced himself into her car and told her to perform oral sex upon him or he would kill her. She fought him off, the records said. In that incident, the man believed to be the Baseline Killer was wearing gloves, a mask and clothing that covered his entire body. The records show police have worked to obtain partial hand prints, DNA and ballistics reports to build their case; but those results were blacked out on the paperwork.

False confession

While being interviewed by police in Kentucky on a burglary case, James Dewayne Mullins claimed responsibility for the murder of Georgia Thompson on September 8, 2005. Mullins told police he shot Thompson as she attempted to rob him outside the Scottsdale strip club where she worked. However, Thompson's body was found almost 10 miles (16 km) away in Tempe at her apartment complex. Police do not believe she was killed elsewhere.

Mullins changed his story when police definitively linked the homicide to the Baseline Killer. Since then, he has told police that he was not in Arizona. Mullins denies any involvement in Thompson's death. On August 3, 2006, murder charges against Mullins were dropped. Authorities stated that Mullins had caused a significant diversion of resources during the hunt for the genuine killer.[7]

Arrest of Goudeau as a suspect

On September 4, 2006, Phoenix police announced an arrest in connection with a sexual assault previously linked to the Baseline Killer while serving a search warrant at 28th Street and Pinchot Avenue.[8]

42-year-old construction worker Mark Goudeau was arrested and charged with attacking two sisters on September 20, 2005 while they were walking home from a Phoenix city park at night. Goudeau was linked to the attack by matching DNA evidence found on the victims. He was tried and convicted on all 19 counts connected to the assault and sentenced to 438 years in prison. Goudeau is still awaiting trial on 74 criminal charges linked to the Baseline Killer investigation.

During the trial, the two sisters gave testimony that Goudeau suddenly approached them with a gun in his hand. They were forced into nearby bushes and told to remove their clothing. The victims said Goudeau sexually assaulted the younger sister as he pointed his gun at the other sister's pregnant abdomen. Prosecutors said Goudeau warned the women not to look at his face during the assault. They also stated he rubbed dirt on one of the women to remove saliva traces, and wore a condom during the assault on one of the sisters.

Maricopa County Attourney Andrew Thomas stated he would seek the death penalty on Goudeau if he is convicted in the murder trial.[3][9]

Goudeau’s wife, Wendy Carr, told The Associated Press that police arrested the wrong man; “My husband is innocent,” Carr reportedly said in a telephone interview. “This is a huge miscarriage of justice. And they have an innocent man in prison. This is all a mistake. He shouldn’t be in prison for something he didn’t do.” Goudeau is described as a loving husband and exceptionally friendly neighbor who took meticulous care of his lawn. Friends and family deny any possibility that Goudeau could be the Baseline Killer, saying he was framed by Phoenix police who were desperate for a suspect.[10][11]

According to Arizona prison officials, Goudeau is an ex-convict who served 13 years of a 21-year sentence for aggravated assault, including beating a woman's head with a barbell, and armed robbery. Goudeau pleaded down to the charge of aggravated assault, but he had also originally been charged with rape and kidnapping. The rape charge was dropped, as there was no physical evidence of rape.

On December 7, 2006, three months after Goudeau was arrested, Phoenix police said they were confident he was responsible for the full series of murders, rapes and robberies that terrorized the city for 13 months. Goudeau is believed to have committed nine murders, one more than originally attributed to the Baseline Killer (the murder of Sophia Nunez on April 10, 2006). Police say ballistics, DNA and circumstantial evidence prove that Goudeau is the Baseline Killer. They are recommending that prosecutors charge Goudeau with 74 crimes, including nine counts of first-degree murder, five counts of sexual assault, three counts of attempted sexual assault, 10 counts of kidnapping, 12 counts of armed robbery, four counts of attempted armed robbery, three counts of sexual abuse, nine counts of sexual conduct with a minor, 13 counts of aggravated assault, and three counts of indecent exposure.[12] On October 31, 2011, Mark Goudeau was found guilty of a total of 67 felony counts, including all murders attributed to the Baseline Killer.[13]

Mishandling of evidence

In April 2009, the Times Publications, a chain of publications in the Phoenix metro area, published a story revealing that the Phoenix Police Department had possessed the key DNA evidence that was eventually used to crack the Baseline Killer case nine months before the arrest, but failed to analyze it in a timely manner.[14]

Another suspect

In June 2009, a leaked police report indicates another suspect had been questioned in connection to the Vargas and Roman lunch truck murder in February 2006. Terry Wayne Smith, a friend of the Goudeau family, has a long, violent history of crime in California and Arizona. Smiths' criminal history includes aggravated assault and armed robbery, plus he was a suspect in two homicide cases.

Smith was released from prison shortly before the Baseline Killer attacks began, and he was arrested a few days after Goudeau. Smith is currently imprisoned for 4 years after allegedly holding his family at gunpoint the night before his arrest. He will be eligible for parole in 2011.[15]

Police officer Rusty Stuart compiled 166 page suggesting that Smith may have been involved in some of the Baseline murders. However, police spokesmen say that Smith had been properly questioned and dismissed as a suspect, and state that Smith was in jail at the time of one of the murders. [16]
