The 16-story Weiguan Golden Dragon complex was the only building to collapse during Saturday's magnitude-6.4 earthquake, which otherwise caused limited damage in the southern city of Tainan.
Government prosecutors have detained three construction company executives on suspicion of professional negligence resulting in death amid accusations that the structure, built in 1989, was not properly reinforced.
A total of 327 people in the building survived. Rescuers say the chances of finding more survivors are now slim.
