A jury found 31-year-old Aaron Demitris Dukes guilty of first degree assault for a January 2012 attack on his then girlfriend. Prosecutors say Dukes walked into the woman's Lakewood home, poured rubbing alcohol on her and lit her on fire.
The woman sustained second degree burns on roughly 12 percent of her body, including her face, according to prosecutors.
Dukes was arrested the following day.
Dukes has a long rap sheet, including felony convictions for robbery, possession of stolen property and domestic violence assault.
The attack on his girlfriend represented his "third strike," which earned him a life sentence.
"The three strike law was enacted to protect the public from violent criminals like Aaron Dukes," Prosecutor Mark Lindquist said in a Friday statement. "The community is safer now that he is permanently behind bars."
