The man, reportedly in his 60s, had repeatedly complained on Facebook to the New Taipei City Government about construction dust caused by renovations at the building. He stated that the dust was affecting residents' health and requested the construction be halted until protective measures were implemented, but his complaints were ignored.

On the morning of his death, he posted a video on Facebook, angrily asking officials, including Mayor Hou Youyi and relevant city departments, if citizens needed to sacrifice their lives to prompt action. That same afternoon, he fell from the fourth floor of the building. Emergency responders found him with no signs of life, and he was pronounced dead at the hospital.

The man identified himself on Facebook as a retired Air Force soldier. His posts detailed the prolonged issues with construction dust and his frustration over the lack of government response. Residents had also reported feeling unwell due to the dust.

New Taipei City Councilor Dai Weishan criticized Mayor Hou and public agencies, questioning their failure to address the complaints and enforce regulations. The Environmental Protection Bureau confirmed receiving complaints on November 10, 12, and 14 but stated that inspections found no dust emissions during their visits. They asked the construction team to strengthen safety measures.

The Public Works Bureau confirmed that the building had received a construction permit in June and stated that safety measures were required under the law. Both bureaus are investigating the incident.
