Law enforcement officials in Texarkana, Texas, are working to obtain an arrest warrant for a Colorado Army officer tied by DNA to several sexual assault cases.
Lt. Aaron Gregory Lucas, 31, is tied to sexual assaults on children in two states. He allegedly lured or tried to lure 11 girls into his vehicle in Colorado, where he is stationed, between 2009 and 2012.
He has pleaded not guilty.
However, he says he is being blamed for the crimes of his twin brother.
In an Oct. 22 court filing, attorneys for Lucas say investigators picked the wrong Lucas 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.
Detective Sgt. Shawn Fitzgerald, an investigator for the Texarkana, Texas Police Department, said detectives believe Lucas “passed through” the Texarkana area when he allegedly committed the kidnapping and aggravated sexual assault of a 7-year-old girl in 2009.
“We are working with the district attorney’s office to get a warrant,” Fitzgerald said.
He said Lucas allegedly kidnapped the girl from a Texarkana, Texas, park and took her behind a strip mall on New Boston Road where he allegedly sexually assaulted her.
“It was a random crime,” Fitzgerald said.
DNA was obtained from the crime and has now been linked to Lucas.
“We were contacted by Alabama about the link,” Fitzgerald said. “That’s the significance of DNA. It is so important to get it whenever there are cases it’s available,” he said.
Lucas’ attorneys, Ted McClintock and Elizabeth McClintock, filed a motion Wednesday asserting that the Alabama and Texas cases involve Lewis’ twin brother, Brian Lucas.
Forensic analysts commonly testify that DNA matches are definitive “in the absence of an identical twin.”
Brian Lucas has not been charged and could not be located for comment.
El Paso County prosecutors say the Colorado victims’ ages ranged from 6 to 9 and that they were targeted at random in Colorado Springs and nearby Fountain by a man who tried to coax them into sex with promises of money and ice cream. Prosecutors contend three girls were assaulted during the encounters.
The incidents began shortly after Aaron Lucas’ arrival at Fort Carson with the First Brigade Combat Team, Fourth Infantry Division.
A Colorado Springs police detective, Fred Walker, has testified the assaults stopped while Aaron Lucas was deployed to Afghanistan.
Aaron Lucas’ attorneys say an unidentified third man is responsible for the Colorado assaults.
Lucas was being held at El Paso County jail on $1.2 million bond. He could face life behind bars if convicted.
