43 | The death of Tony Dyson, R2D2 Builder (Star Wars), on March 4, 2016

Tony = 2+6+5+7 = 20
Dyson = 4+7+1+6+5 = 23/32
Tony Dyson = 43/52

Tony = 20+15+14+25 = 74
Dyson = 4+25+19+15+14 = 77
Tony Dyson = 151

Notice his name corresponds with his date of death, March 4, which in most parts of the world is written 4/3.

RIP = 18+9+16 = 43
March 4, 4/3

3/4/2016 = 3+4+20+16 = 43
3/4/2016 = 3+4+2+0+1+6 = 16
3/4/16 = 3+4+16 = 23

With regards to '68', it reminds of how caskets go 6-feet deep and are often 8-feet long.

Malta?  That reminds me of the Order of Malta.  It also has a connection to 'Star Wars'.

Malta = 13+1+12+20+1 = 47
Star Wars = 1+2+1+9+5+1+9+1 = 29/38/47
