This 22 March 2018 video from the USA says about itself:
Mark Anthony Conditt, 23, has been identified as the person behind a string of deadly bombings in Austin. He blew himself up as police tried to arrest him on Wednesday. The serial Austin bomber had been part of a Christian survivalist group that would discuss weapons and dangerous chemicals – as authorities reveal he had a target list of future locations to continue his reign of terror.

Mark Conditt reportedly had a much more deadly plan to end his bombing rampage. …
As part of his homework for an Austin Community College government class, he kept a blog for a few months in early 2012 in which he detailed conservative views on topics including same-sex marriage (he was against making it legal) and terrorism (he was against cutting deals with al Qaeda operatives).
A BuzzFeed report revealed that Conditt had been active in a Bible study group called Righteous Invasion of Truth (RIOT) that focused on outdoor survival skills, including how to shoot guns and use knives.
Authorities have warned that he may have planted or mailed other bombs prior to his death and have asked residents to stay vigilant.
