Police believe Jason "JT" Ready is responsible for shooting four people and taking his own life in a suburban Phoenix home. Authorities say that the four others killed were 15-month-old Lily Lynn Mederos; 23-year-old Amber Nieve Mederos; 47-year-old Lisa Lynn Mederos and 24-year-old Jim Franklin Hiott.
Media reports say Lisa Mederos was Ready's girlfriend and Amber and Lily were her daughter and granddaughter.
Ready was known in Arizona for organizing a militia in the desert with the goal of finding illegal immigrants and drug smugglers. The 39-year-old outfitted himself with military fatigues, body armor and gas masks. He also carried assault rifles. Police say he was a former Marine with ties to Neo-Nazi and Minutemen groups.
