Authorities discovered bomb-making sketches and materials in his storage unit, including electronic circuit boards and timers, alongside extensive internet searches on bomb-making dating back to 2017.

Yener had attempted to join extremist groups like the Boogaloo Bois and the Proud Boys but was denied due to his radical views and desire for martyrdom.

This arrest is part of a broader trend, following other recent national security arrests related to domestic threats against U.S. officials and landmarks.

In a police interview, he confessed to previous attempts to join domestic extremist groups and considered fighting for ISIS in Iraq.

He claimed to have been recruited by ISIS via Facebook Messenger, although he ultimately declined the offer.

The U.S. Attorney's Office for the Southern District of Florida announced the arrest of Yener on November 20, 2024, following his expressed intentions to carry out a bomb attack.

Yener communicated to undercover FBI agents his plan to detonate a bomb targeting the stock exchange, claiming it would 'wake people up'.

He referred to the potential attack as a 'great hit', describing the execution as 'hella easy' and indicating plans to disguise himself while sending a message to the media afterward.

In October 2024, Yener was seen purchasing tools at Walmart for building an improvised explosive device (IED), further demonstrating his intent.

Yener expressed to agents that he was waiting for the right moment to execute his attack, stating, 'I’ll know it when I see it.'

If successful, he intended to target oil rigs next, emphasizing that he felt he had nothing to lose.

During his interactions with the agents, Yener sought assistance in procuring explosives necessary for constructing the bomb.
