Wednesday makes it the first time Randolph Oates has visited the Aldi market where police officers shot his son.  "He was a loving kid, a loving kid. When he was right, very caring. Loved his family, he was very good with computers," said Randolph Oates.  He says his son was homeless and dealing with an extreme mental illness when he shoplifted food from the nearby Dollar Tree store before the shooting.  According to police, Emanuel Oates pulled out a machete and tried to attack responding officers. Police said he ran into the Aldi store and then charged at them with the machete before they shot him several times.
