3d printed gun inventor dies of heart attack at age 28, days after his house was raided by police

He invented and publicized a totally 3d printed gun (unlike previous/other ones that required purchase of a bolt or magazine to be bought the old fashioned way). Every part of it except the barrel, which could be made at home as well. His gun was called FGC-9 ('fuck gun control 9mm').

He was raided after financial companies reported his unusual purchased to law enforcement, reportedly.

Many raised questions about his death, having occurred so soon after a raid by a force related to those who probably investigated and confirmed the normalness of his death (they reported he had a heart defect), combined with his age.

However, 1 in 5 heart attacks are now for people under age 40. That means 0.3% of people between 20 and 40 have heart attacks. However, the average age for a first heart attack is 65 for men and 72 for women.

Note, though, that having a heart attack is not the same as dying from a heart attack, I don't think, anyway. I didn't see stats for dying of heart attack under age 30.
 
Quotes said by the guy, JStark, on YouTube: "There are certain circumstances in our life that are unfortunate, and which make living kind of painful, and sometimes I do not have anything to look forward to. But with me, I have nothing to lose. And to accept the risk to be able to die at any time basically. Live free or die. These are not empty words.  ... We do not want harm for anyone. We want everyone to live peacefully amongst each other. And we want people to have the freedom of speech and the right to bear arms. If that's too politically extreme for you, fuck yourself."
