KANSAS CITY, Mo. (AP) — A Kansas man has pleaded guilty for his role in a Missouri home invasion robbery during which three people were killed.

The Kansas City Star reports 23-year-old Raul Soto of Kansas City, Kansas, admitted in federal court Tuesday that he and several co-conspirators went to an Independence, Missouri, home in November 2012 to rob a man they believed had a large amount of methamphetamine.

The home’s residents denied having any drugs. Three of the occupants — Maria Hernandez, her boyfriend Thomas Dominguez-Gregorio and her son, Antonio Hernandez — where fatally shot.

Soto admitted in his plea that he was armed with a handgun and killed Antonio Hernandez. Under terms of the plea deal, attorneys will recommend a 27-year prison sentence.

Four others already have pleaded guilty in the case.
