The odds are astronomical that DNA recovered from a possible rape victim doesn’t belong to a Phoenix man arrested by the task force investigating the Baseline Killer, court documents state.
Prosecutors laid out some of their case in court documents against Mark Goudeau, 42, who is accused of a Sept. 23, 2005, rape of two sisters, one of 23 rapes, robberies and slayings attributed to the Baseline Killer since August 2005. Authorities continue to investigate the other crimes.
The court document says the Arizona Department of Public Safety crime lab tested swabs from the breast of one of the victims and determined that the likelihood the DNA belongs to “someone other than the victims and the defendant were one in 240 trillion.”
Goudeau’s defense attorney, Corwin Townsend, did not return a phone call seeking comment Friday.
Defense attorney Larry Hammond, who is not affiliated with the case but agreed to discuss DNA evidence, said there may still be questions about whether the sample was contaminated, manipulated, or if it is a mixture of the victim and defendant, which would make it less reliable.
“In the absence of that, what they’re really claiming is this is a dead-bang match,” said Hammond, who heads The Justice Project, a group that seeks to help those who may have been wrongly convicted.
Prosecutors intend to present the evidence at a Dec. 5 evidentiary hearing, during which they will ask that Goudeau be held with no bond. He is currently jailed in lieu of $1 million cash.
Aside from the DNA, the state intends to tell Judge James Keppel of Maricopa County Superior Court that police found clothing in Goudeau’s home similar to that described by the victims.
And even though one of the victims picked someone else out of a photo lineup, Goudeau’s appearance is similar to the man she chose, prosecutor William Clayton wrote.
