Aaron Lucas’ lawyers also say that, while Lucas’ twin was behind the crimes in Alabama and Texas, another man was responsible for the assaults in Colorado.

An Army officer linked by DNA to sexual assaults on children in three states claims his identical twin brother Brian is really to blame for some of the crimes.

In the case in Colorado Springs, Colo., 1st Lt. Aaron Gregory Lucas, 32, has already pleaded not guilty to accusations that he lured or tried to lure 11 young girls ages 6 to 9 into his vehicle in Colorado between 2009 and 2012.

Prosecutors said the victims were chosen at random and a man tried to draw them into sex with promises of money and ice cream. They said these encounters, which started soon after Aaron Lucas arrived at Fort Carson, resulted in three assaults.

Colorado Springs police detective Fred Walker testified that the attacks halted while Aaron Lucas was deployed to Afghanistan, according to the Colorado Springs Gazette.

Aaron Lucas is also assault allegations in Alabama. There he is charged with child enticement and sexual abuse of a child younger than 12 in Madison

In addition, in Texarkana, Texas, officials said they are waiting for the district attorney’s office to approve an arrest warrant that lists charges similar to those in both Colorado and Alabama.

But attorneys for the Fort Carson, Colo., artillery officer said in an Oct. 22 court filing in the Colorado case that investigators tied the wrong Lucas brother to the 2007 attack on a girl in Alabama and a 2009 assault on one in Texas.

Aaron Lucas’ defense attorneys are requesting that their team be permitted to suggest in court that Brian Lucas was behind the Alabama and Texas assaults.

The motion also asserts that another man altogether is responsible for the Colorado incidents, according to the Gazette.

Forensic analysts usually say that DNA matches are definitive “in the absence of an identical twin.”

Records found online do appear to confirm that Aaron Lucas has a brother named Brian who shares his birthday and lived in both Alabama and Texas.

However, Brian Lucas has not been charged with anything.

Aaron Lucas is being held in a Colorado jail on $1.2 million bond as he awaits trial in that state, set for Jan. 4. He could face life behind bars if convicted.
