Let us begin with the name 'Nia Wilson'.
Notice the 44 in reduction, that's the key number.
African-American = 44 (Septenary)
Kill = 44 (Ordinal)
MLK on 4/4
Malcolm X on 2/21/1965 (2+21+(1+9+6+5) = 44)
Thomas Hagan = 44 (Reduction) (X's assassin)
Today's date also has 67 numerology.
7/22/2018 = 7+22+20+18 = 67 (BART = 67) (Killer = 67) (Blood Sacrifice = 67)
Even more, this story has parallels to the killing of Oscar Grant at the BART stop.
He was murdered at age 22, Nia Grant was murdered on the 22nd day of July.
Murder = 79 (Ordinal); 79, the 22nd prime number
Notice the 116 and 44 overlap... Execution = 44 / 116
As for the 44 and 64 in Oscar Grant, that connects to 'kill'.
ALSO noteworthy, the other woman injured in this more recent incident is Letifah Wilson, a name with Gematria of 63, like 'racism', and reminding of the Emmett Till case being opened up after 63-years passing since his death.
The killer's name has a lot do with Freemasonry, and Oakland, where this happened.
Negro = 59; Slave = 59; Blues = 59; Kill = 59 (Jewish)
Notice how his surname connects to 'racist'.
7/22/18 = 7+22+18 = 47 (Racist = 47)
And one more point about the 59 in the name John Lee Cowell. Keep in mind this killing supposedly happened at MacArthur Station.
