FT. CARSON, Colo. (KUSA) - An Army lieutenant in Colorado stands accused of sex crimes in three states. Authorities say several children are among his victims.
But there's a shocking twist to this case. In a motion filed recently, he's claiming that his identical twin brother is responsible for the sexual assault in Colorado.
A married father of two, 1st Lt. Aaron Gregory Lucas is still considered active duty. Investigators say during his service at Fort Carson in Colorado Springs, he lured or tried to lure 11 young girls into his car.
The children were all between 6 and 9-years-old. Prosecutors say Lucas sexually assaulted three of them.
His lawyers have filed a new motion asking a judge if they can implicate another man for those Colorado crimes. A man they say "bears a striking resemblance" and drove a similar car.
Lucas is also accused of a rape in Texas and Alabama. In those cases, his lawyers say Lucas's identical twin is to blame. Our research shows Aaron Lucas does have a twin brother, Brian. Both were born in July 1981.
"Identical twins share the same DNA but they do not have the same fingerprints," said legal analyst Scott Robinson. "What the defense will do will be to try to put in doubt the eye witness accounts of course the DNA match using the fact that the other brother shares the same DNA profile."
Lt. Lucas has a glowing military resume; 10 medals and awards in his four years of active duty, including a Bronze Star.
Investigators in Colorado Springs say the crimes against the young girls started shortly after he started his service at Fort Carson, and stopped when he left for Afghanistan.
Lt. Lucas faces 23 charges that could send him to prison for more than 100 years if he's convicted on every count. His trial is scheduled for January.
