A convicted killer of two undercover NYPD detectives impregnated a guard at a federal prison, hoping to avoid the death penalty, reports the New York Daily News.

Federal agents arrested the guard, Nancy Gonzalez at her Long Island home on Tuesday. She is eight months pregnant with the child of Ronell Wilson, who was convicted in 2006 of fatally shooting Detectives Rodney Andrews and James Nemorin during a gun-buy bust in 2003.

Gonzalez faces 15 years in federal prison if convicted.
