Hydrazine is easy to set off and to synthesize from household chemicals (relatively), but it's never been used in these IEDs as far as I know. Probably because of how toxic, corrosive, and unstable it is, and has to be combined with a nitrogen agent anyway (like another kind of hydrazine and I think ammonia nitrate would work). That makes it not only difficult to handle safely, but only a couple steps from ANFO anyway.

HTP is also easy to set off.

Anyone ever accidentally make 'grinder thermite'? It's where the dust by a grinder or cutting wheel builds up from use and burns. Sweeping up isn't just to keep the shop tidy!

Investigators have his list of "future targets" which are residences and they can't find anything linking them to each other. There is no apparent theme or target motive. He's like an equal opportunity serial bomber with no particular hatred or aim other than killing.

Interesting. Seems like it's been a while since we've had a bona fide old school serial killer.

I think that Paddock in Las Vegas was the same. I suspect that Cruz at Parkland is also in that group.

Those weren't serial killings.

You're right, those are spree or mass. There was a serial killer last summer or fall. A young black guy shooting homeless and random people. I forget what area that was. He got caught. Didn't seem to have any outstanding problems and from a good family. He just wanted to kill.

Lethal Exploding Packages in Austin, Texas

Although I am not a big fan of the surveillance state and its capabilities, it must be noted that serial killers are becoming rare occurrence. And when they occur they kill far less people than they did for instance in the 1970s.

The combination of bank details, cameras, license plate registration , mobile phone data is having a big impact.

Just like serial robbers like Bonnie and Clyde promptly stopped existing after police cars were fitted with radio.

Maybe people who would otherwise have become a serial killer‘s are now becoming mass murderers.

Perhaps a few of them share a similar mindset, but I think the prevalence of shooters and rampage killings is also unwittingly perpetuated by mass media. But they are important events we cannot ignore. A poster here once suggested that the killers should remain anonymous in news reports, but I think that's a silly solution
.
I think the first major rampage shooting known countrywide began with Charles Whitman, then some lesser known shootings, then Columbine, then general massacres almost everywhere else as this type of behavior was seen and absorbed by other loners and angry disturbed individuals.

Most serial killers appear to kill for pleasure, sex and violence being apparently closely linked.

Most rampage killers appear to be motivated by some deep seated rage or out of control spite. I mean when I had problems controlling my anger I would pout and pout and sometimes intentionally close doors on people, as a mild case. I was selfish and didn't care how many women I was rude to. I think rampage killing is an extreme version of that, also behavior shared by suicide pilots and in some murder suicides. It's scary because they can seem so normal.

One of his two roommates is now considered a person of interest. I guess he knew about the bombs. No details reported yet.
