The bombings at the Boston Marathon have left us all reeling and wondering when or if this sort of thing will EVER stop. They've also made me wonder why this specific week is so particularly volatile.

It's unreal how many historic tragedies have occurred around this time. On April 15th, 1912, the RMS Titanic hit and iceberg in the North Atlantic and sank, killing more than 1500 passengers and crew members.

On April 16th, 2007, a lunatic named Seung-Hui Cho shot and killed 32 people and wounded 17 others at Virginia Polytechnic Institute and State University, more commonly known as Virginia Tech.

It's been nearly 30 years since a suicide bomber drove an explosives-laden delivery van into the U.S. embassy in Beirut, Lebanon on the afternoon of April 18th, 1983, killing 63 people, including 17 Americans.

On April 19th, 1993, the siege at the Branch Davidian complex in Waco, Texas ended violently with an FBI assault that led to a fire which destroyed the compound. 76 members of the Branch Davidian sect were killed.

Exactly two years later, a fertilizer bomb was detonated at the Alfred Murrah Federal Building in Oklahoma City, killing 168 people. Timothy McVeigh was sentenced to death for the bombing and was executed in 2001. Co-conspirator Terry Nichols is serving a life sentence.

And on April 20th, 1999, the entire nation was riveted as details began to unfold of a horrific mass shooting at Columbine High School in a Denver suburb. Gunmen Eric Harris and Dylan Klebold, who were also students, killed 13 students and faculty members and wounded 21 more before turning the guns on themselves.

I know there's nothing we can glean from these bizarre and horrendous coincidences. Who knows why this particular week in history has been such a deadly one for so many?
