[5] When Birdland closed, Orgaoow sold the building and lot to Westwood Entertainment Company, Inc.'s owner and president Hermilo Ocampo.

[6][7] Initially, the Ocampos planned to use the site for residential reasons but the family instead converted it to a discotheque, noting the rise of electronic music in the Philippines.

[8] Survivors reported seeing sparks flying inside the disc jockey's booth shortly before midnight, followed by smoke which they thought was part of the DJ's party plan.

[7] The final death count was reported as between 160[11] and 162 people, the latter being the figure cited by the trial court that heard the ensuing criminal case.

[7][11] On March 16, 2001, the president of Westwood Entertainment, Hermilo Ocampo, and the corporation's treasurer, Ramon Ng, were found guilty by a Quezon City trial court and sentenced to a four-year prison term, and fined 25 million pesos each.

They were accused of allowing Ozone Disco to secure a certificate of annual inspection in 1995 "despite the inadequacy, insufficiency and impropriety of the documents submitted by the owners".

They were held liable for negligence in connection with the approval of the building permit and issuance of certificates of occupancy for the company which owned Ozone.

[15] The structure, which housed the Ozone Disco, remained standing in Timog Avenue, Quezon City but was not commercially used for over 20 years after the incident.
