This inflatable art took off and plumeted killing two persons in London. People were inside it at the time it crashed on top of people on the ground. The first time I read about this the interrior was shown, now you just see the deflated art sculpture. It went up because it was a hot day, and it became lighter than air.
Ant other killer art that you know of?
The artist Christo erected a bunch of umbrellas outside of Los Angeles as some kind of work of art. A few of them ended up getting blown loose and a woman was hit and killed by one.
In June 2006, artist Luis Jimenez was crushed by one of his sculptures when it fell over while it was being moved.
Argh that’s horrible. How bewildering that must have been! 
And to add to Santos’s post about Christo, here’s a link from Wiki about it. Sadly, not one but two people died. The information is under the “Umbrellas” section. There’s also a Luis Jimenez page that details his death, by a sculpture of a mustang intended for the Denver International Airport.
Killer Art!
Back in the mid-90’s there was an artist in Seattle who abandoned his beater car with 'bomb" painted on it, obliging the authorities to treat it as a legitimate bomb scare (we had a pit thread recently about a London artist who did the same thing with a parcel in the Underground). I couldn’t give him much praise for this contibution to the sum total of human artistic achievement, although I did send a letter to The Stranger which they threw away, recalling a play by Guillaume Apollinaire during WWI when an actor dressed up as an English officer threatened to shoot a few rounds into the audience. Apollinaire reasoned that, since it was a realistic act to shoot at people wearing certain uniforms, it was a surrealistic act to shoot at people regardless of what they wore.
Richard Serra once killed a studio worker when one of his massive sheets of steel which he like to make houses of cards with collapsed. But life is short and art is long, and Serra emerged from his guilty funk to dazzle the art world with more rusty slabs. (What was really long was his “Titled Arc,” a big, wide piece of steel that blocked foot traffic in NYC.)
Chris Burden had himself shot in the arm with a rifle; not killer but rather wounding art. One installation of his had a huge steel mill wheel with a jacked-up motorcycle spinning it around. Those present were overcome with the realization “Shit! If that wheel comes off, we’re all dead!”
Then there’s art that kills its creator by its chemistry. Eva Hess was already sick, but she was helped along by the materials she used to make plastic sculptures.
Rudolf Schwarzkogler leads the killer art field, as those wacky, blood-spattered Viennese should, with his death after slicing off his penis while wrapped as a mummy. Luckily, it never happened, but it sure makes a great addition to any art history lecture.
Wow Slithy, that last guy, Schwarzkogler, apparently killed himself (according to this site). And if you simply Google his name, you’ll get a hit for THE VIENNA AKTIONISTS and it contains some very interesting works on “ultrabizarre,” “infamous,” “subversive” and “extremist performance art” which I’d rather not link to because it wouldn’t be work safe and I’m not sure how to make it beyond the two click rule. All long before NIN was a household name. 
I think I’ll search for him on eBay now, so thanks for the head’s up.
There were many painters—pretty much any time before the last 50 years–who died from licking their brushes (makes a nice point, don’t you know) because the dyes in the paint were toxic. Caused a lot of insanity, too, before the deaths.
Adolf Hitler, artist and dictator, who created World War II as a performance piece on the theme of man’s inhumanity to man.
