COLORADO SPRINGS, Colo. -- A judge says an Army artillery officer linked by DNA to a string of sexual assaults on young girls will be allowed to blame his twin brother at trial for attacks in two states.
District Judge David Shakes ruled Friday it would be "inappropriate" to bar 1st Lt. Aaron Lucas' attorneys from presenting his identical twin as an alternate suspect given the siblings' shared DNA, according to the Colorado Springs Gazette (http://bit.ly/1agdX2C).
"Whether it's persuasive or not -- that's not my role," the judge said. "It's the role of the jury."
In criminal prosecutions, DNA is widely considered a smoking gun, but only in the absence of an identical twin.
In an Oct. 22 court filing, Lucas' attorneys said investigators picked the wrong sibling after discovering a DNA link to an unsolved attack on a young girl in Madison, Ala., in 2007, and another in Texarkana, Texas, in 2009.
The Fort Carson, Colo., officer has denied luring or trying to lure 11 girls into his vehicle in Colorado between 2009 and 2012. His attorneys have said the Alabama and Texas cases involve his twin brother, Brian Frederick Lucas, who the defense says has lived in both states.
Brian Lucas, who has not been charged in any of the cases, could not be reached for comment Saturday but investigators have said he has denied involvement in the alleged crimes.
Aaron Lucas' attorneys say an unidentified third man is responsible for the Colorado assaults.
Investigators say that a DNA test linked Aaron Lucas to the abduction of an 8-year-old girl in Colorado Springs and that he also matched biological material recovered in the Alabama and Texas cases. The Colorado judge has ruled that the out-of-state evidence will be allowed at trial.
Lucas is scheduled to appear in court Nov. 26. His attorneys did not return a message left by The Associated Press on Saturday.
