April 19th-20 are dates of some significance for white supremacists and others inclined toward hatred.
Oklahoma City bombing 4/19, Columbine shooting 4/20 and others.
Maybe some connection? Maybe not...
So this attack ended on the 25th anniversary of the OKC bombing, and the 2018 Toronto van attacks happened on Timothy McVeigh's 50th birthday.
The December 6, 1989, Ecole Polytechnique Massacre in Montreal happened on the anniversary of the 1917 Halifax explosion (~2000 dead), which itself happened on the 10th anniversary of the worst ever US mine disaster. The shooter had a denture office in Dartmouth, near Halifax (about 2 miles from 1917 explosion).
April 18 = San Francisco earthquake (Herbert Mullin)
April 19= OKC bombing (and Waco siege ends in inferno)
April 20=Columbine, Hitler's birthday
April 21=Belvidere/Oak Lawn tornado two days before James Earl Ray escapes from Missouri Penitentiary
April 22, 1992=Adam Lanza born in Exeter, NH, same day as Guadalajara sewer explosions (252 dead)
April 23=Ray escapes in '67 and dies in '98, Timothy McVeigh born in '68, Toronto van attack in 2018.
On April 23, 1968 (one year anniversary of Ray's escape), RFK was campaigning in Indiana on what the media called the
Wabash Cannonball campaign train (same route and perhaps borrowing of train set) from Logansport to Fort Wayne. On June 8, 1968, the day Ray was caught at Heathrow Airport, two spectators of RFK's southbound funeral train in Elizabeth, NJ, who could not clear themselves of the track in time, were killed by a northbound Penn Central train shortly before 2 pm (I think about 4 am, June 9, in Port Moresby, Papua New Guinea). On June 9, 1942, in Port Moresby, Papua New Guinea, at about 8:30 am, LBJ left his seat on a B26 preparing for takeoff nicknamed (according to most sources) the
Wabash Cannonball in order to urinate, and upon his return, he had to change planes because another observer, Colonel Francis Robert Stevens, had grabbed his seat. While under attack by Japanese Zeros in the same TOW 9 mission, the
Wabash Cannonball crashed into the sea, killing all on board.
