OTTAWA, Kan. (AP) — Prosecutors are calling the crimes of an eastern Kansas man convicted in a quadruple homicide "extremely wicked, shockingly evil and vile." The Topeka Capital-Journal reports that the sentencing phase of Kyle Flack's trial began Monday. The jury is hearing testimony to determine if the 30-year-old should be sentenced to death. Flack was found guilty last week of capital murder in the 2013 deaths of Kaylie Bailey and her toddler daughter, Lana. Flack also was convicted in the deaths of Bailey's boyfriend, Andrew Stout, and his roommate, Steven White, at a rural Ottawa farmhouse. Senior assistant attorney general Vic Braden says the killings of mother and daughter were done in an "especially heinous, atrocious or cruel manner." The defense hasn't yet made its case for life imprisonment.
