But experts say tinkering with homemade explosives is dangerous because of the volatility of materials used. Shrapnel from the devices themselves, as well as dirt and stones, can injure and even kill, they say. Hyche, who retired a year ago from the Bureau of Alcohol, Tobacco, Firearms and Explosives as an explosives specialist. Hyche, who is now a police chief in Alabama after serving at ATF for three decades, said the blast pressure wave from an explosion can be as deadly as shrapnel.

He said illegal bomb builders typically order chemicals that are used in pyrotechnics like commercial fireworks. Paul Smith, president of Pyrotechnics Guild International in Indiana, said the chemistry involved in making such concoctions is challenging, even for experts. Smith said he has a degree in chemistry and works in the fireworks industry as a hobbyist. He also said he has an ATF license to manufacture fireworks.

Those in his industry work with such chemicals to create artistic displays to entertain people, not to be destructive for kicks, he said. Hurst police say they received a tip on Feb. Police arrested Nelson outside his apartment, and neighbors were evacuated.

A bomb unit searched the residence and found explosive materials, the department said. Ammonium nitrate is a common ingredient in explosive devices and has been used in multiple terrorist attacks, including the Oklahoma City bombing. Nelson was released from jail on bond. Around this time, his last video was posted to Improvised Chaos, court records show. After getting out of jail, Nelson wrote on his channel that police caught him with only a small amount of explosive material and no completed bombs.

I set off everything as it was made. The channel has more than 40 videos, the first of which was posted in July , and slightly more than subscribers. In videos posted to the channel, Nelson filmed himself lighting fuses and then scrambling away before showing the impact blast in a wooded area.

He shows his hands but not his face in the narrated videos. He felled a large tree in one video. In another, he stands inside a deep crater in the ground, gouged out by one of his explosions.

Nice damage. But on April 7 around 4 p. Whatever his links with Dagestani rebels, five months ago Tsarnaev posted two revealing videos. They feature a little-known jihadist leader, Abu Dujana, making a rambling speech to "Muslim youth".

Abu Dujana wears military fatigues and holds a Kalashnikov. He speaks in Russian. Two other armed rebels — their faces hidden by scarves and balaclavas — sit next to him, against a black Islamist flag.

His tiny group named itself after Rabini Kallikov, a local militant killed by Russian security forces in or In December, months before the Boston attacks, Russian police in turn killed Abu Dujana during a raid on his Makhachkala flat.

Cerwyn Moore, an expert on the insurgency in the North Caucasus at Birmingham University, said of Tsarnaev's video post: "He's obviously aware of some of the clandestine groups operating in Dagestan.

This is a small sub-group. Abu Dujana is not a big player. Federal forces have been successful recently at killing all the top leaders. Tsarnaev listed the two videos under the category "terrorism". Later he — or someone else — deleted them. Other videos on his YouTube account star impressionable young men talking, in Russian, about their conversion to Islam: spiritual journeys of transformation that seem to echo Tsarnaev's own.

One, Mikhail, is from Pyatigorsk, in the North Caucasus; another shares his experiences from a Yekaterinburg mosque. There are also songs by Timur Mutsurayev , a religious Chechen singer whose ballads have been classified by Russian courts as "extremist". It is possible that the account he created has at some point been interfered with, but there is no obvious sign of that.

One video talks about his beliefs, prayers and ablutions as a good Muslim. He speaks about leading a meaningful life; almost the very last word is "peace. The video praises women for wearing the full Islamic veil.

Another video posted suggests a growing Salafist viewpoint, one common to militant Sunnis such as the Taliban in Afghanistan. It includes remarks by a Salafist sheikh, Abdul Hamid al Juhani, and references to the Salafist "brothers" from Chechnya as well as the violence in Syria. It also includes inflammatory remarks against Sufi Muslims -- a frequent target of militant Sunnis. Photos: Photos: Suspects tied to Boston bombings.
