The Minnesota Attorney General's office will review the case of a woman accused of killing her husband in southern Minnesota, then fleeing to Florida and killing a woman there.

Lois Riess has not been charged in the fatal shooting of her husband, 54-year-old David Riess, at the couple's home in Blooming Prairie last March. Dodge County Sheriff Scott Rose says his investigators were at a "standstill" waiting for a handgun recovered from Lois Riess' hotel room after her arrest in Texas to be released by Florida authorities for ballistic testing in Minnesota.

Rose says testing by the Minnesota Bureau of Criminal Apprehension indicates the shell casings found at David Riess' homicide matched the handgun.

Authorities say Lois Riess went to Fort Myers, Florida, met Pamela Hutchinson while there and killed her to assume her identity. She remains jailed in Florida in Hutchinson's death.
