Two Kansas City-area men have been charged in a triple homicide in Independence that prosecutors say was motivated by robbery and a search for drugs.

Jackson County prosecutors Wednesday night announced charges of first-degree murder and other counts against 32-year-old Antonio Cervantes, of Independence, and 33-year-old Kevin Finley, of Kansas City.

Both are accused in the early-morning home invasion and shootings Nov. 16. Killed were 48-year-old Maria Hernandez; her 20-year-old son, Antonio Hernandez; and her boyfriend Tomas Dominguez, previously identified as Tomas Madrigal.

A 12-year-old boy was also shot trying to protect his mother, and continues recovering from critical injuries.

Police said in court documents that Cervantes was the stepson of Dominguez and had previously robbed him of $30,000.
