The Prosecutor's Office is investigating a criminal organization that has been bribing local officials to secure public works construction contracts. The five mayors are suspected to have participated in a corruption scheme that granted illegal benefits to the MECO construction company.
The OIJ deployed 40 raids across the country, over 600 agents, and 32 prosecutors, who also raided offices in the Escazu, Siquirres, and Golfito city halls. Likewise, investigators raided the Public Works and Transportation Ministry (MOPT) and other construction companies.
The Prosecution stated that officers are investigating the alleged advance payment of invoices, the early approval and start of public works, and bribes associated with road maintenance. The program for public road works is mostly financed by a loan from the Inter-American Development Bank (IADB).
In June, the MECO irregularly won a public tender against a consortium which submitted a cheaper offer. In that month, this company and the National Highway Council were also involved in the Cochinilla case, a corruption scandal that ended with 30 detainees, 14 of whom were public officials.
The investigation showed that MECO bribed authorities with liquor, money, vehicles, and sexual services to secure public contracts. This procedure generated a fiscal deficit of over US$120 million between 2018 and 2020.
